One household fitting
You want one 250 mm pair for a basin waste, a toilet cistern nut or a hose, and 32 mm is enough. The Blue Spot 06436 is about £5.76, with 4.7 from 641 reviews. A push-button and an unmarked chrome finish are not the point.
Fitting pliers comparison 2026
The best fitting pliers, compared.
Top pick: Blue Spot 250 mm box-joint water pump pliers – Highest score in the set: about £5.76, 4.7 from 641 reviews, a printed 250 mm box joint and 32 mm opening, with household UK notes. Best value: HAUTMEC 180 mm push-button fitting pliers – About £12.99 for the cheapest push-button in the set, with 180 mm, a 42 mm opening and a claimed pinch guard, after the shared 193-review parent line. Updated October 2026.
Fitting pliers, sold in the UK as water pump pliers or plumbers' grips, hold and turn pipe fittings, compression nuts, valves and irregular stock. A joint that stays in its notch or button hole, a jaw opening that matches the nut, and a tooth or smooth face that matches the surface decide the row. Jaw, opening and joint are set out in the [fitting pliers buying guide](/hub/pliers/fitting-pliers/sub/fitting-pliers-buying-guide). A printed opening or a weight line is the listing figure, not a measurement taken for this page.

The best fitting pliers in detail
Our view
The Blue Spot 06436 is a single 250 mm box-joint water pump plier at £5.76, 380 g, with a listed 32 mm opening and 4.7 from 641 amazon.co.uk reviews. The bullets name drop-forged, heat-treated, epoxy-coated steel and a fully polished finish, plus a lifetime warranty line. UK notes are household jobs rather than daily trade, and they describe a joint that can feel stiff at first and handles that can slip when wet. The listing does not name a V-jaw, a pinch guard, or a standard. 32 mm is the same opening as the HAUTMEC auto 250 mm pair, so this is not the large-nut tool in the set.
Pros
- £5.76, the lowest price in this set
- 4.7 from 641 amazon.co.uk reviews
- Box joint, 250 mm, and 32 mm opening all printed
- UK notes cover toilet-seat and basin-waste jobs
Cons
- 32 mm opening, no pinch-guard line
- Joint can feel stiff at first
- Handles can feel slippery when wet or oily
Best for: You want one 250 mm household pair for a cistern nut or hose clip and you do not need a 40 mm-plus opening.
Less suitable: You need a push-button, a pinch guard, or jaws that will take a large waste nut.

Common questions
How wide do the Blue Spot jaws open?
The listing says a maximum jaw opening of 32 mm on a 250 mm / 10 inch pair. There is no pipe-diameter line beyond that figure.
Are the blue handles insulated for live electrics?
No. The material line is alloy steel and thermoplastic rubber, with plastic soft-grip handles. There is no BS EN IEC 60900 or VDE line.
What do UK reviews use them for?
Household plumbing in the sample: toilet seat, basin-waste back-nut, outside-tap hose, a kitchen-tap attachment. One review finds the joint a little stiff at first; another says the handles get slippery when wet or oily.
Our view
The HAUTMEC HT0366-UK is a 180 mm push-button V-jaw pair at £12.99 and 230 g, with a 42 mm opening in the jaw bullet and a claimed pinch guard. The 4.5 from 193 reviews is shared with the 300 mm sibling, so it is not a unique 180 mm sample. Shared UK notes compare the pattern to cheaper Knipex, praise the button against a slip-notch joint, and also report a handle that slid off, play between the halves, and jaws that only fully close on the lowest setting. The listing does not cite BS ISO 8976. Comfort plastic is not insulation.
Pros
- 180 mm and 42 mm printed; 230 g is a credible mass
- Push-button and pinch guard claimed
- UK notes on basin-waste and tight spaces
- £12.99, the cheapest push-button in this set
Cons
- Star line shared with the 300 mm sibling
- Handle-off and joint-play notes in the parent sample
- Serrated V-jaw, no plated-fitting line
Best for: You want a compact push-button pair for a basin waste and will check the handle covering on arrival.
Less suitable: You need a unique review sample, a 70 mm-class opening, or jaws that will not mark chrome.

Common questions
Is the 4.5 from 193 unique to the 180 mm pair?
No. The same 4.5 from 193 line sits on the 300 mm sibling B0DQVFPZNN. Treat it as a parent variation, not two independent samples.
Does the listing name a pinch guard?
Yes. The bullets claim a powder-metallurgy fast-adjust button and an anti-pinch safety guard. There is still no live-work mark.
What opening does the 180 mm pair claim?
The jaw bullet says 42 mm. A separate cutting-width field says 180 mm, which matches the handle length, so the comparison uses 42 mm from the jaw bullet.
Our view
The HAUTMEC HT0368-UK is a 300 mm push-button V-jaw pair at £18.99 with a 75 mm opening in the bullet and a claimed pinch guard. The listing is rank 1 in Tongue-and-Groove Pliers, but the 4.5 from 193 reviews is shared with the 180 mm sibling. The details block prints 10 g and 30 × 30 cm, which are not credible tool figures, so the listing is incomplete even where the length and opening look useful. Shared UK notes praise a button they compare with a Knipex-style joint, and also report a handle covering that slid off and play between the halves. No BS ISO 8976 line. Not a live-work tool. The 75 mm opening was not measured here.
Pros
- 300 mm length and 75 mm opening in the bullets
- Push-button and pinch guard claimed
- Same parent notes that like the button versus a slip-notch joint
Cons
- Weight line 10 g and 30 × 30 cm dimensions
- Star line shared with the 180 mm sibling
- Handle-off and joint-play notes in that parent sample
Best for: You need the longest pair in this set and will weigh and inspect it on arrival.
Less suitable: You want a listing whose mass and review sample are unique and credible before you pay £18.99.

Common questions
Does the listing really weigh 10 g?
That is the figure in the details block. It is not a credible mass for a 300 mm steel plier. The 180 mm sibling lists 230 g. This comparison does not invent a replacement weight.
How wide is the 300 mm opening?
The jaw bullet and the cutting-width line both say 75 mm. That figure was not measured here.
Is the review count separate from the 180 mm pair?
No. 4.5 from 193 is the same parent line as B0DQVFTJ66, including the handle-off and joint-play notes.
Our view
The HAUTMEC HT0088 is a 250 mm auto-adjust V-jaw pair at £14.99 and 390 g, with a 32 mm / 1¼ inch opening, the same capacity band as the Blue Spot 250 mm. The listing sells a one-hand spring with no button. UK reviews used it on a toilet-handle nut and a shower bar, and they also report jaws that do not meet, teeth that chipped on first use, and a spring that disappeared on conduit. The item-type line says 3PCS while the unit count is 1. There is no pinch-guard line and no standard. 4.4 from 290 includes overseas text; the failures above are UK lines.
Pros
- 250 mm and 32 mm printed; 390 g is a credible mass
- One-hand spring take-up claimed
- UK notes of a toilet-handle nut and a shower bar
Cons
- UK notes: jaws not meeting, teeth chipped, spring lost
- Same 32 mm opening as the £5.76 Blue Spot pair
- Item-type 3PCS versus unit count 1; no pinch guard
Best for: You specifically want a spring auto-adjust 250 mm pair and will inspect the teeth and spring on the first jobs.
Less suitable: You want a button rack, a pinch guard, or a 250 mm pair without first-use chip and spring complaints in the UK sample.

Common questions
Is this a three-piece set?
No on the count that matters for the box. Included components is “Pliers” and unit count is 1.0. The item-type name says “3PCS Tongue and Groove Joint Pliers Set”.
Does auto-adjust mean a Cobra-style button?
No. The listing says no buttons and no channels to lock: squeeze and the spring takes up. UK reviews call it clever but a learning curve. Overseas notes on the same page say it does not spring open like Knipex.
What failures appear in UK reviews?
Jaws that do not meet, teeth chipped on first use, and a spring that auto-tightens gone after about three days on galvanised conduit. The tool in that last review still worked without the auto action.
Our view
The GEINXURN GXP09B-MIX-DE is sold as a £25.99 three-piece smooth-jaw pliers wrench, 1.59 kg, with openings 38 / 50.8 / 63.5 mm in the bullet and a plated-fitting claim. 4.4 from 21 is a small sample, and several UK reviews describe two 250 mm tools rather than 180/250/300 mm. Those notes like the smooth jaws and the second pair for holding, and they dislike a stiff push-button and a scale window with no numbers. Position count is 24 in the title and 15 in a bullet. German-marketplace text on the same page is not treated as UK evidence. No pinch-guard line and no standard.
Pros
- Only smooth-jaw set in this comparison
- Openings printed for three lengths
- UK notes of plastic caps and a second pair to hold
Cons
- 4.4 from only 21 reviews
- UK reviews of two 250 mm tools versus the 3-piece title
- Stiff button and a scale window without numbers
Best for: You want smooth jaws for plated nuts and will confirm the pack is 180/250/300 mm before you keep it.
Less suitable: You need serrated teeth on round pipe, a large UK review sample, or a listing whose piece count matches the reviews.

Common questions
Is this a serrated water pump plier?
No. The title is a pliers wrench with a smooth V-jaw, aimed at plated fittings. The other four ASINs in this set are serrated water pump pliers or an unnamed box-joint pair.
Do you always get three lengths?
The title, unit count 3.0, and included components say 180/250/300 mm. Several UK reviews on the same page describe two 250 mm pliers instead.
How many lock positions are there?
The title says 24. A bullet says 15. Reviews also say 15, 18, 19, or 24. The listing does not agree with itself.
How we compared
Five fitting pliers on amazon.co.uk were scored on 19 October 2026 from listing facts and review notes, not from a grip test. Amazon evidence, listing fit, review outcome and value are weighted 30, 35, 20 and 15. Deductions come off for a small or shared review sample, a weight or piece count that does not match the tool, chipped teeth, a lost spring, a handle that slides off, or a button that will not slide. Each star line stays the amazon.co.uk figure. The 0–100 score is not the stars times 20. Comfort grips are not scored as live-work insulation.

Fitting pliers buying guide
Start with the jaw and the surface, then the opening and the length, then the joint. Price comes after those three. The notes below follow that order for these five amazon.co.uk listings, checked on 19 October 2026. None of the scores is a grip test.
What are fitting pliers?
Fitting pliers, sold in the UK as water pump pliers or plumbers' grips, are multiple-slip-joint tools for holding and turning pipe fittings, compression nuts, valves and irregular stock. Screwfix treats water pump pliers as the plumbing plier. On amazon.co.uk this set is five listings, from about £5.76 to about £25.99, checked on 19 October 2026. They were not lab-tested. A printed opening or a weight line is the listing figure, not a measurement taken for this page.
Best for
- One 250 mm household pair for a basin waste, cistern nut or hose when 32 mm is enough
- A push-button 180 mm in the bag, with a 300 mm pair when the opening or the leverage is the point
- Show chrome or plated hex, where smooth jaws or a cloth matter more than serrated teeth
Not ideal for
- Live conductors, including anyone reading a comfort grip as insulation
- Gas pipe, boilers and combustion cases, which are Gas Safe work
- A three-piece title when the UK reviews describe two tools of the same length
Mistakes to avoid
- 1
Serrated jaws on chrome
A serrated V-jaw marks plated hex and chrome pipe. DIY Doctor’s advice is a non-serrated tool or a cloth. In this set the smooth-jaw title is the GEINXURN, not the four serrated or unnamed rows.
- 2
The wrong length for the space
180 mm on a large waste nut, or 300 mm in a pedestal void, is the size mistake. Housewarm’s household first size is 250 mm. Match the printed opening to the nut before you buy length for leverage alone.
- 3
Believing the piece-count line
The HAUTMEC auto item-type line says 3PCS while the unit count is 1. The GEINXURN title says three lengths, and several UK reviews describe two 250 mm tools. Read the unit count and the UK notes together.
What to weigh up
Jaw and surface
HighSerrated V-jaws bite round pipe, damaged nuts and work you do not mind marking. They mark chrome. Smooth parallel jaws, plastic caps or a cloth are the plated-nut tool. DIY Doctor’s note on chrome pipe is a non-serrated tool or a cloth. In this set the three HAUTMEC rows are serrated V-jaws. The Blue Spot listing does not name the jaw. The GEINXURN title is a smooth V-jaw pliers wrench, with a plated-fitting claim and UK notes of plastic jaw caps. That is the only smooth-jaw row.
Opening, length and joint
High180 mm is the void and bag size. Housewarm treats 250 mm as the household first size and 300 mm as the length for large plastic cistern nuts and extra leverage. Blue Spot and the HAUTMEC auto pair both list 32 mm. The HAUTMEC 180 mm lists 42 mm. The 300 mm lists 75 mm, which was not measured here. GEINXURN lists 38 mm, 50.8 mm and 63.5 mm. Classic grooves, on the Blue Spot box joint, are simple. A push-button sets the jaw on the workpiece.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
A compact pair in the bag
You change size often and you want a push-button 180 mm rather than a groove joint. The HAUTMEC HT0366-UK is about £12.99, with a 42 mm opening and a claimed pinch guard. Check the handle covering on arrival. The 4.5 from 193 is shared with the 300 mm sibling.
Plated nuts and chrome
You are working on show chrome or plated hex, and serrated teeth would mark it. The GEINXURN set is about £25.99 and is the only smooth-jaw title here. Confirm the pack is 180/250/300 mm, because several UK reviews describe two 250 mm tools.
Common questions about fitting pliers
Which fitting pliers are the top pick in this set?
The top pick is the Blue Spot 06436, about £5.76 on amazon.co.uk. It is a 250 mm box-joint pair with a listed 32 mm opening, 380 g, and 4.7 from 641 reviews. UK notes cover a toilet seat, a basin-waste back-nut and an outside-tap hose. The same notes say the joint can feel stiff at first and the handles can slip when wet or oily. The score uses those listing facts. It is not a lab test, and 32 mm is not a large waste-nut opening.
How much do fitting pliers cost on amazon.co.uk?
On these five amazon.co.uk shelves, checked on 19 October 2026, prices run from about £5.76 to about £25.99. Blue Spot is about £5.76. The mid singles are the HAUTMEC 180 mm push-button at about £12.99, the auto-adjust 250 mm at about £14.99, and the HAUTMEC 300 mm at about £18.99. The GEINXURN smooth-jaw set is about £25.99. The 4.5 from 193 on the two push-button lengths is one parent line. These bands are this set only, not a survey of every water pump plier on sale.
Should you buy serrated jaws or smooth jaws?
Serrated V-jaws bite round pipe, damaged nuts and work you do not mind marking. They mark chrome and plated hex. Smooth parallel jaws, plastic caps or a cloth are the finish-safe choice. DIY Doctor’s advice on chrome pipe is a non-serrated tool or a cloth. In this set only the GEINXURN title is a smooth-jaw pliers wrench, at about £25.99. The other four are serrated, or the Blue Spot listing does not name the jaw. A separate smooth-jaw comparison is pliers wrench.
What length and opening should you look for?
Use 180 mm in a void or a bag, 250 mm as the household first size, and 300 mm when the nut is large or you want more leverage. Housewarm sets out those three lengths. Blue Spot and the HAUTMEC auto pair both list 32 mm. The HAUTMEC 180 mm lists 42 mm. The 300 mm lists 75 mm, which was not measured here. GEINXURN lists 38 mm, 50.8 mm and 63.5 mm. Match the opening to the nut. Length alone does not tell you the jaw will fit.
Is auto-adjust the same as a push-button?
No. A push-button, on the HAUTMEC 180 mm and 300 mm and on the GEINXURN, sets the opening on the workpiece. The HAUTMEC 250 mm auto-adjust has no button in the bullets. A spring takes up as you squeeze. UK reviews call that a learning curve, not two-way Cobra adjust, and one UK note says the spring vanished after about three days on galvanised conduit. A spring, button or handle that fails on arrival is a Consumer Rights Act 2015 returns issue.
Can you use fitting pliers on gas pipe or live conductors?
No. Gas Safe Register says there is no DIY on gas-carrying parts or combustion cases, including boilers. Call a Gas Safe engineer for that work. None of these five listings cites BS EN IEC 60900. ISO 5743 treats plastic handle coats as comfort, not electrical insulation, so these are not live-work tools. On a workplace, pliers are work equipment under PUWER 1998. What the site box still has to cover is set out in PUWER toolbox tools.
When should you call a plumber?
Call a plumber when the joint is inaccessible, the system will not isolate, or you cannot make a workmanlike compression joint. The Water Supply (Water Fittings) Regulations 1999 expect fittings of appropriate quality and joints you can still reach. Grips on a buried joint do not make that work legal DIY. Housewarm’s method is the grips on the fitting body and a spanner on the nut. A 180 mm pair on a large waste nut, or a 300 mm pair in a pedestal void, is a size mistake.
Our verdict
In this set of five amazon.co.uk listings, the top pick is the Blue Spot 06436. It is about £5.76, a 250 mm box-joint pair with a listed 32 mm opening, 380 g, and 4.7 from 641 reviews. UK notes are household jobs, with a joint that can feel stiff at first and handles that can slip when wet. The best value is the HAUTMEC HT0366-UK at about £12.99, 180 mm, a 42 mm opening and a claimed pinch guard. The 4.5 from 193 reviews is shared with the 300 mm sibling, and those notes include a handle that slid off. The other three have no award. None of these scores is a lab test, and none of these tools is rated here for live work or gas pipe.
