Short dry hobby joints
You cover soldered electronics and short low-voltage leads, and 45 mm pieces are enough. The Electrapick kit lists 2:1, 1 mm to 13 mm, in a case, at about £6.64. No adhesive is stated.
Heat shrink tubing comparison 2026
The best heat shrink tubes, compared.
Top pick: Tooxwire 250-piece kit Best value: Zuchini 164-piece kit – Readable 2:1 list from 1.0 mm to 14.0 mm at about £3.49, 4.5 from 2,448 reviews, with the smallest sizes called thin. Updated 22.10.2026.
Charlie White (Charlie DIYte)Expert source
Heat shrink tubing is precut sleeving, or a cut length, that recovers when you heat it. You use it to cover a soldered or crimped joint, or to tidy a hobby or vehicle lead. Piece count and a large star line do not settle the choice. Some titles conflict with their own specification, and some reviews describe another variant or come from outside the United Kingdom. Tell the packs apart by expanded diameter, recovered grip, and whether adhesive is listed when a seal is required. None of these 12 names a BS EN 60684 sheet. On fixed wiring, a sleeve is not the enclosure BS 7671 asks for. How to read diameter and ratio is in the [heat shrink tubing buying guide](/hub/electrical-equipment/heat-shrink-tubing/sub/heat-shrink-tubing-buying-guide). You do not use it in place of a junction box.

The best heat shrink tubes in detail
Our view
The Tooxwire 250-piece kit is £13.99 of adhesive-lined pieces at 45 mm and 90 mm, in six imperial sizes from 1/8 in to 3/4 in, listed as 4:1. The star line is 5.0 from 7 reviews. The two stored texts are from the United States, so this file has no United Kingdom review. One of those texts calls the ratio 3:1 while the title says 4:1. Weight is 540 g, which is the heaviest kit in the set. The components line says excluding components. The listing was first available on 2 September 2025. The mixed lengths are a real listing fact. The five-star line is not a UK result, and the ratio is already argued in the only detailed text on file.
Pros
- 45 mm and 90 mm adhesive pieces across six diameters
- Dual wall is stated
- 540 g, so the pack is not a light bag
Cons
- No UK review in the sample
- A stored review calls the ratio 3:1 against a 4:1 title
- £13.99 with only seven published reviews
Best for: You want both short and 90 mm adhesive pieces and you will judge the ratio yourself.
Less suitable: Anyone who needs a UK review of this ASIN before paying the joint-highest price in the set.

Common questions
Are there UK reviews in the extract?
No. The listing line is 5.0 from 7. The two stored texts are from the United States. One of those calls the ratio 3:1 while the title says 4:1.
What lengths are listed?
45 mm and 90 mm, six diameters from 1/8 in to 3/4 in, adhesive lined. Weight is 540 g.
Our view
The Xinsuo 300-piece kit is £9.99 of black and red pieces at 45 mm and 90 mm, in five imperial sizes from 2/32 in to 3/8 in, listed as 4:1 with a hot-melt inner layer. The amazon.co.uk line is 5.0 from 1 review. That United Kingdom text, dated 3 October 2026, likes the idea of an adhesive inner wall and does not report a finished job. Weight is 50 g beside a 300-piece count. The material line is polyethylene. Flame retardancy appears as a recommended-use line, and no 60684 sheet is cited. The 90 mm pieces are the useful difference from a 45 mm-only kit, and one review that does not describe a joint is not a result you can lean on.
Pros
- Hot-melt lining and a 4:1 ratio are both stated
- 45 mm and 90 mm pieces in five sizes
- Black and red
Cons
- One review, and it does not describe a finished joint
- 50 g next to a 300-piece count
- No standard sheet for the flame line
Best for: You want the 90 mm adhesive lengths on the label and you can check the box yourself.
Less suitable: Anyone using a five-star line from a single review as the reason to buy.

Common questions
What does the single review say?

Is a standard named?
No. Flame retardancy appears as a recommended-use line. No 60684 sheet is cited.
Our view
The Electrapick 560-piece kit is 560 black pieces, each 45 mm, in 12 diameters from 1 mm to 13 mm, listed as 2:1, in a partitioned case, at £6.64. The amazon.co.uk line is 4.7 from 941 reviews, and the file holds 50 United Kingdom texts. Those texts praise the case and the size range. One reviewer wanted the pieces longer, which is the limit of a 45 mm precut once you allow for the joint and a little overlap onto the insulation. No adhesive is stated, so this is a dry cover, not a seal. Weight is 228 g. The part number in the extract is UKCZ0000505-E0130. It is the top pick in this set because the diameters, the length, and the ratio are all on the page and the review file is large enough to read, with the short piece as the trade-off against the cheaper 164-piece kits.
Pros
- 12 diameters from 1 mm to 13 mm, each piece 45 mm
- 2:1 stated, 560 pieces in a case, at £6.64
- 4.7 from 941 reviews, with 50 UK texts
- Case and size range praised in UK reviews
Cons
- Pieces called short
- No adhesive stated
- Material field is blank
Best for: A boxed black 2:1 kit for short indoor joints where 45 mm is enough.
Less suitable: A seal, a 1 m sleeve, or a joint that needs more than 45 mm after you overlap the insulation.

Our view
The Eventronic 600-piece kit is £8.49 of 45 mm pieces in 12 diameters from 1 mm to 13 mm, and the title also says 27 m. The listing line is 4.6 from 54,164 reviews. The 50 stored UK texts describe more than this SKU, including a 560-piece pack, a 90 mm adhesive set, and a 2017 butt-connector review, so that star line is not a verdict on these 600 pieces. The bullets say EVA and halogen-free. The specification says polyolefin and self-adhesive. Shrinkage is stated as up to 50 percent at 90–120 °C, which is a 2:1-style claim rather than a measured higher ratio. Bullets name IP56, ISO 9001:2008, SGS, CE and RoHS, and no 60684 sheet. Weight is 200 g. Buy it only if you accept that the material, the adhesive line, and the review pool do not agree with each other.
Pros
- Twelve diameters and a stated 45 mm length
- A temperature band is printed on this listing, 90–120 °C
- Five colours are listed
Cons
- The 54,164 ratings mix other Eventronic variants
- Bullets say EVA; the specification says polyolefin and self-adhesive
- IP56 is a bullet, not a named sleeving sheet
Best for: You already have this box and you treat the 45 mm and 1–13 mm lines as the usable facts.
Less suitable: Anyone choosing from the star count, or anyone who needs one material and a confirmed lining.

Are the 54,164 ratings all for this 600-piece kit?
The listing line is 4.6 from 54,164. The 50 stored UK texts also describe a 560-piece pack, a 90 mm adhesive set and a 2017 butt-connector review.
Our view
The Lsnisni sleeve is a 2 m adhesive-lined length listed as 3:1, at £10.99. The size field says 30 mm. The title lists 7.9, 15.4, 19.1, 30 and 40 mm, so one page is offering a range and a single size at once. The star line is 4.6 from 128 reviews. Four of 50 stored texts have a United Kingdom dateline. One UK review ordered 30 mm as a flat width and measured 48 mm flat. Another says it starts at 60 mm wide. Both say it then shrank enough for their job. Weight is 200 g. The model line is 30-31-2M, and the colour field says 30 mm, which is a size rather than a colour. Buy the 2 m lining if a long adhesive sleeve is the point, and measure the flat width when it arrives.
Pros
- 2 m of double-wall tubing with adhesive stated
- 3:1 is the listed ratio
- Two UK reviews say it shrank enough after a wider flat measurement
Cons
- Flat width in UK reviews did not match a 30 mm order
- The title lists several diameters; the size field says 30 mm
- Only four of 50 stored texts are UK
Best for: A long adhesive sleeve for one large low-voltage cover, checked with a ruler on arrival.
Less suitable: A kit of small precuts, or a flat width you must hit at 30 mm.

The Boloest set is five adhesive-lined lengths, 12, 16, 20, 32 and 40 mm, 1 m each, listed as 4:1 in PE and EVA, at £13.99. The star line is 4.6 from 17 reviews. Four of 12 stored texts are United Kingdom datelines. A review on 28 June 2026 calls the sizes useful and says the recovery felt a little over 2:1 rather than 4:1. Weight is 420 g. The manufacturer field says Zhibao Store. The outside-diameter field says 40 mm, which is the largest size in the set rather than a single tube you can assume for every length. No standard sheet is named. This is the large-diameter row. The 4:1 title is the figure that UK review says the tubing did not recover to.
Pros
- Five 1 m lengths from 12 mm to 40 mm
- Adhesive listed, with PE and EVA named
- A UK review calls the diameters useful
Cons
- That review puts recovery a little over 2:1, not 4:1
- 4.6 from 17 reviews, with four UK texts in a sample of 12
- £13.99, and the components line says no
Best for: Thick low-voltage cables where you need 20–40 mm expanded tubing in metre lengths.
Less suitable: Fine wire, a measured 4:1, or a small precut kit.

What is in the pack?
Five diameters, 12, 16, 20, 32 and 40 mm, 1 m each, adhesive lined, PE and EVA. No standard sheet is named.

The Zuchini 164-piece kit is the £3.49 assortment with a stated 2:1 ratio, five colours, and eight diameters from 1.0 mm to 14.0 mm. Across 2,448 amazon.co.uk reviews the line is 4.5, and the file holds 50 United Kingdom texts. A 25 March 2026 review says the two smallest sizes only suit very thin strands, and that the tubing does shrink. Other UK texts use a heat gun or a lighter on model and lamp leads. No adhesive is stated, so a tight sleeve here is insulation, not a seal. Piece length is not on the extract. The material line is cross-linked polyethylene. At this price, with diameters you can read, it is the best value in the set, with the limit that the smallest tubes are for fine wire.
Pros
- 2:1 listed, with 1.0 mm to 14.0 mm in eight sizes
- 4.5 from 2,448 reviews, and 50 UK texts in the file
- Five colours at £3.49
- Cross-linked polyethylene named
Cons
- Smallest sizes called too thin for anything but fine strands
- No adhesive stated
- Piece length not listed
Best for: Dry indoor joints and hobby leads where you want colours and a readable 2:1 size list.
Less suitable: A seal, a metre length, or green-and-yellow identification.

The Huakayo 507-piece kit is £9.99 of black precut pieces listed as 5:1 dual wall with adhesive, in seven imperial sizes from 3/32 in to 3/4 in, each about 1.77 in. The star line is 4.5 from 120 reviews. Thirteen of 48 stored texts are United Kingdom datelines. UK comments that are specific praise the adhesive and a hot-air gun on the sizes they tried. One UK review is titled barely 3:1 and calls the 5:1 title false advertising. Weight is 310 g. The listing was first available on 3 February 2026. No British Standard sheet is named. The lining is listed, and the 5:1 figure is the claim that UK review says the buyer did not get.
Pros
- Adhesive-lined dual wall is stated
- Seven sizes with piece counts, about 1.77 in long
- Some UK texts praise the adhesive on the sizes they tried
Cons
- A UK review says recovery was barely 3:1, not 5:1
- Only 13 of 48 stored texts are UK datelines
- No 60684 sheet is named
Best for: A black adhesive kit if you accept the lower recovery that UK review describes.
Less suitable: Anyone who needs a measured 5:1, or a metre of one diameter.

Common questions
What ratio is printed, and what does a UK review say?
The title says 5:1. A UK review is titled barely 3:1 and calls that false advertising. Thirteen of 48 stored texts are United Kingdom datelines.
Is adhesive listed?
Yes. The listing says adhesive-lined dual wall, and that the adhesive quantity is higher than on 3:1 tubing. No British Standard sheet is named.
Our view
The Huakayo length set is £9.99, listed as 12 m of 5:1 adhesive-lined tubing across seven diameters from 3/32 in to 3/4 in. The colour field says Clear. The star line is 4.5 from 69 reviews, and six of 47 stored texts are United Kingdom datelines. A UK review on 17 September 2026 says the tubing arrived as folded lengths of about 30 cm, not as the rolls in the pictures. One UK review says it does not shrink at 5:1. Weight is 170 g. The foot lengths on the size lines are what the page adds toward the 12 m claim, and the form that arrived in that review was cut lengths. Treat the adhesive line as listed, and treat rolls and 5:1 as disputed.
Pros
- Adhesive-lined dual wall is stated
- Seven diameters with foot lengths printed
- £9.99 if folded lengths are what you wanted anyway
Cons
- A UK review says pieces of about 30 cm, not rolls
- A UK review says it does not shrink at 5:1
- Colour field says Clear, and only six of 47 texts are UK
Best for: You want adhesive-lined cut lengths and you will not rely on a roll or on 5:1.
Less suitable: A continuous reel, a confirmed 5:1, or a colour you take from the Clear field.

The Zatyorg 127-piece kit is £3.49 of black tubing listed as 2:1, and the star line is 4.4 from 1,100 reviews. A bullet lists seven internal diameters from 2.0 mm to 13 mm, while the title says 12 sizes, so the count on the page does not match itself. Fifty UK texts are in the file. Reviewers say it shrinks with a heat gun and is long enough for a butt connector if the tube goes on first. Others wanted smaller diameters, a clearer size list, and longer pieces. Piece length is not stated. No adhesive is stated, and the material field is blank. Weight is 30 g. You can use the bullet diameters, and you should ignore the 12-sizes line when you count what will be in the bag.
Pros
- 2:1 stated, with seven diameters written in a bullet
- 4.4 from 1,100 reviews
- UK texts say it covers a butt connector if the tube is on the wire first
Cons
- Title says 12 sizes; the bullet lists seven
- Diameters called large and pieces called short
- No adhesive and no piece length
Best for: A black 2:1 cover for ordinary leads when you follow the seven-diameter bullet.
Less suitable: Fine electronics wire, a seal, or a size count you take from the title.

The Daryunk 164-piece kit is £3.49 of multicolour polyolefin listed as 2:1, with 4.3 from 106 reviews and 31 UK texts in the file. The extract does not list the diameters in millimetres. A UK review on 31 August 2026 says yellow is scarce, there is no green-and-yellow, and not to buy it for UK wiring identification. A review on 30 August 2026 says pieces stayed loose and some caught fire and melted. Other UK texts say the diameters covered soldered joints. No adhesive is stated, and the warranty line says no warranty. Weight is 30 g and the dimension line is 10.5 x 10.5 cm. The price matches the other entry kits, and the missing size list plus the melt report are the reasons to pass if you need a predictable tube.
Pros
- 2:1 polyolefin stated at £3.49
- 164 pieces in a box
- Some UK texts say the diameters covered soldered joints
Cons
- One UK review reports pieces that caught and melted
- No millimetre size list
- No green-and-yellow in a UK review that checked the colours
- Warranty line says no warranty
Best for: A cheap colour mix for dry hobby joints if you can check the diameters once the box arrives.
Less suitable: Protective-conductor colours, or a size list you need before you order.

Our view
The Blunivia 127-piece kit is a £2.99 pack of black PE pieces with seven sizes named and no millimetre on the extract, so you cannot match a lead before you order. The amazon.co.uk line is 4.3 from 5 reviews, and the two stored United Kingdom texts are short: one says excellent selection, the other says it does the job, with Heat gun as the title. Neither names a defect, and neither says which diameter fitted which cable. The listing does not state 2:1 or any other ratio, so a recovered diameter cannot be worked out from the page. The package line is 4 x 3 x 1 cm and the weight is 11 g beside a 127-piece count, which is a conflict rather than a measured volume. There is no adhesive line. It is the cheapest row in this set, and it is also the row that gives you the least to check before you heat a piece.
Pros
- £2.99 for 127 black pieces
- Two short UK reviews name no defect
- PE is named as the material
Cons
- No ratio and no millimetre diameters
- Package size and 11 g sit next to a 127-piece count
- Only five reviews, two of them stored
Best for: You already know the diameters you need and you only want a cheap black top-up.
Less suitable: You need a recovered diameter, adhesive, or a size list you can measure against a lead.

How we compared
Twelve heat shrink tubing listings on amazon.co.uk were scored on 21 October 2026 from the stored listing lines and UK review notes, not from a shrink test. A printed ratio, a temperature or a waterproof line is a listing claim. Amazon evidence is 25: the star rating scaled against 5, then multiplied by a count factor that falls when the UK text is thin or describes another variant. Listing fit is 40: diameters you can read, a ratio UK reviews have not already disputed, a stated piece length, and an adhesive line only where the file states one. Review outcome is 20: UK texts that describe shrinking, a short piece, a melt, or a ratio the buyer did not get. Value is 15: the shelf price in GBP against the job the file supports. The lowest price does not win when the diameters are missing. The weights sum to 100. The highest score is the top pick. Once that place is filled, the best value is the readable 2:1 list at about £3.49 with a large UK review file.

Amazon evidence
25%The amazon.co.uk star rating is scaled against 5, then multiplied by a count factor and rounded. The factor is 1.0 only when the published count is 200 or more and at least 20 UK texts were stored. It falls when the count is small, when few of the stored texts are from the United Kingdom, or when those texts describe another variant.
2
Listing fit
40%Points rest on diameters you can read, a ratio that UK reviews have not already disputed, a stated piece length, and an adhesive line only where the file states one. A title that disagrees with its own bullet, a material pair that disagrees, or a roll a UK review received as folded lengths, lowers this part. No 60684 sheet is named on any of the twelve, so a standard claim does not add points.

Review outcome
20%UK texts that describe shrinking, a case, a short piece, a thin small size, a melt, or a ratio the buyer did not get set this mark. No UK body means a low mark. A text that only likes the idea of adhesive, without a finished joint, stays low.

Value
15%Shelf price in GBP is set against the job the listing actually supports. The lowest price does not win when the diameters are missing. The dearest kit does not win when the sample has no UK review.

Heat shrink tubing buying guide
Start with the expanded diameter, then the listed ratio, then whether adhesive is stated, then the piece length. The star line comes after those four. The notes below follow that order for these 12 amazon.co.uk listings. None of the scores is a shrink test.
What is heat shrink tubing?
Heat shrink tubing in this set is precut sleeving, or a cut length, that recovers when you heat it. You use it to cover a sound soldered or crimped joint, or to tidy a hobby or vehicle lead. You do not use it in place of a junction box. These 12 amazon.co.uk listings run from about £2.99 to £13.99. A piece count, or a very large star line, does not tell you the diameter or the wall.
Best for
- A dry cover on soldered electronics or a short low-voltage lead, if you can live with 45 mm pieces
- A vehicle, boat or outdoor low-voltage splice where adhesive is listed, and you treat a 4:1 or 5:1 title as a claim
- A black 2:1 kit with diameters and a piece length you can read before you order
Not ideal for
- A joint inside a wall, a consumer unit, or any fixed wiring that needs an enclosure under BS 7671
- Anyone sorting by piece count, or by Eventronic’s 54,164 rating, instead of diameter and ratio
- Green-and-yellow identification, or a waterproof claim taken from a title that does not state adhesive
Mistakes to avoid
- 1
Sorting by piece count or the star line
Electrapick is 560 pieces and Zuchini is 164. Eventronic’s 4.6 from 54,164 mixes other variants, including butt connectors. The useful lines are the diameters, the ratio, and whether a UK review describes this pack.
- 2
Reading one millimetre as diameter and flat width
Lsnisni’s size field says 30 mm. One UK review ordered that as a flat width and measured 48 mm flat. Another says it starts at 60 mm wide. Both said it then shrank enough. Measure the tube that arrives.
- 3
Using a sleeve as the enclosure
A sleeve can cover a sound joint on a hobby or vehicle lead. It is not the accessory or enclosure BS 7671 asks for on a live conductor. A hobby colour pack is also not green-and-yellow identification.
What to weigh up
Diameter and shrink ratio
HighMatch the expanded diameter to the widest point the tube must slide over, then the recovered diameter to the cable. GTSE uses about 20–30 percent clearance. HellermannTyton’s UK catalogue uses an 80:20 rule of thumb: at least 20 percent of the shrink, and not more than 80 percent. A single millimetre figure is not both a round diameter and a flat width. On Lsnisni, UK reviews measured a wider flat width than 30 mm and then said the sleeve still shrank enough for their job.
Wall, length and the review file
HighPlain tubing is for a dry cover and for marking. Adhesive-lined dual wall is what you read when moisture or an uneven low-voltage splice matters. An IP56 line is not a test report. Electrapick, Zuchini, Zatyorg, Daryunk and Blunivia do not state adhesive. Huakayo, Xinsuo, Lsnisni, Tooxwire and Boloest do. Eventronic says self-adhesive on the specification and EVA in the bullets, against polyolefin on the same specification. Many kits are 45 mm precuts.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
A low-voltage splice that needs adhesive
You want a lining on a vehicle, boat or outdoor low-voltage joint, and you will not treat a 4:1 or 5:1 title as measured. The Boloest set lists adhesive and five 1 m lengths from 12 mm to 40 mm, at about £13.99. A UK review puts recovery a little over 2:1.
A lead that is not fixed wiring
A sleeve is not the joint and not the enclosure if the cable is inside a wall or a consumer unit. For a short dry cover on a lead that is not fixed wiring, the Electrapick kit is the top pick in this set. Call a competent person for the fixed circuit.
Common questions about heat shrink tubes
Which heat shrink tubing is the top pick in this set?
The top pick is the Electrapick 560-piece kit, about £6.64, with 4.7 from 941 amazon.co.uk reviews. The listing states 2:1, 12 diameters from 1 mm to 13 mm, and 45 mm pieces in a case. Fifty UK texts praise the case and the size range. One reviewer wanted the pieces longer. No adhesive is stated. The score is 89. That is not a lab test, and no 60684 sheet is named.
How much does heat shrink tubing cost on amazon.co.uk?
On these 12 shelves, checked from the stored amazon.co.uk lines, Blunivia is about £2.99. Zuchini, Zatyorg and Daryunk are about £3.49. Electrapick is about £6.64 and Eventronic is about £8.49. Both Huakayo listings and the Xinsuo kit are about £9.99. Lsnisni is about £10.99. Tooxwire and Boloest are about £13.99. The lowest price is not best value here, because Blunivia lists no ratio and no millimetre diameters. Prices will move.
Should you buy 2:1 tubing or an adhesive-lined sleeve?
Buy a stated 2:1 single wall for a dry indoor cover. Electrapick and Zuchini both list 2:1, and Zuchini adds colours from 1.0 mm to 14.0 mm. Buy adhesive-lined tubing when moisture or an uneven low-voltage splice matters. Huakayo, Xinsuo, Lsnisni, Tooxwire and Boloest state a lining. An IP56 line in a title is not a test report. A sleeve still does not replace an enclosure on fixed wiring.
Does heat shrink tubing enclose a joint under BS 7671?
No. BS 7671:2018 Regulation 526.5, as Professional Electrician sets it out, says a joint in a live conductor needs a suitable accessory, an equipment enclosure, or an enclosure finished with non-combustible building material. A heat shrink sleeve is not that enclosure. Approved Document P covers electrical work in dwellings in England. Use a sleeve on a sound hobby or vehicle lead. Do not use one to close a joint inside a wall or a consumer unit.
Can you trust a 4:1 or 5:1 title?
Not as a measured result. A listed 2:1 recovers to about half the expanded diameter, and 3:1 to about one third. This page did not measure either. UK reviews dispute 5:1 on both Huakayo listings and put Boloest a little over 2:1 rather than the 4:1 title. A stored Tooxwire review calls a 4:1 title a 3:1 recovery. Treat a high ratio as a claim until you have shrunk a spare piece on the cable you actually have.
Does Eventronic’s 54,164 rating describe this 600-piece kit?
No. The amazon.co.uk line is 4.6 from 54,164 reviews. The bullets say EVA, and the specification says polyolefin and self-adhesive. The 50 stored UK texts also describe a 560-piece pack, a 90 mm adhesive set and a 2017 butt-connector review. That pool is not a verdict on this 600-piece variant alone. The usable facts on the page are the 45 mm length and the 1 mm to 13 mm diameters. No 60684 sheet is named.
When should you call a competent person?
Call a competent person for fixed wiring, a damaged fixed circuit, work that may be notifiable under Part P, a burnt mains flex, and any workplace repair. A sleeve can cover a sound joint. It does not make a 230 V repair inside a wall acceptable. A crimp still needs the right terminal before any sleeve goes over it. See cable terminals for that fitting. The sleeve is still not the enclosure.
Our verdict
In this set of 12 amazon.co.uk listings, the top pick is the Electrapick 560-piece kit. It is about £6.64, with 4.7 from 941 reviews, a stated 2:1 ratio, 12 diameters from 1 mm to 13 mm, and 45 mm pieces in a case. The score is 89. UK reviews praise the case and call the pieces short. No adhesive is stated. The best value is the Zuchini 164-piece kit at about £3.49, with 4.5 from 2,448 reviews, five colours and eight diameters from 1.0 mm to 14.0 mm. The score is 86. The smallest sizes are called thin, and piece length is not listed. None of these scores is a lab test. A sleeve in this set does not enclose a fixed-wiring joint.
