Gas cartridge or cylinder BBQ

Updated: 16.10.2026

You already own a cupboard of Campingaz cartridges, or a green Calor patio-gas bottle, and the new grill’s hose will fit only one of them. By the end you should know which of these nine listings matches the container you can refill, and why butane fades on a cold evening. A gas cartridge or cylinder BBQ is two appliances, not one gas with a clever adaptor. The [small gas grills comparison](/hub/portable-grills/small-gas-grills) shows the fuel column. This page is the decision. The Products Compared editorial team used the stored amazon.co.uk listings from 15 October 2026 and Calor, Hamilton Gas Products, and the Camping and Caravanning Club. A qualifying purchase can earn a commission at no extra cost to you.

Two systems, not one gas

A Campingaz CV cartridge is a small sealed container, clipped under a stove-grill. A patio-gas bottle is a 5 kg or 13 kg propane cylinder, feeding a hose through a regulator. Hamilton Gas Products states 37 mbar for propane and patio gas, and 28–30 mbar for butane. The data plate wins if the instructions differ. Calor’s hose guide lists a 27 mm clip-on for green patio bottles, a 21 mm butane clip-on, and a screw-on propane regulator. You do not join a Party Grill to a Calor bottle by stacking those fittings. Campingaz sells a twin-connection kit for a CV470 Plus or a refillable Campingaz cylinder, one source at a time, including some Party Grill 400 R stoves. That kit is not in the included line of the Party Grill 400 CV here. If the soapy-water test on a new hose still bubbles, stop. The sequence is on the how to use page. The buying guide covers burners and weight.

Which listing is which

The original Party Grill at £43.92 names CV300 and CV470 cartridges. The Party Grill 200 at £56.01 names a CV470 Plus, with a bullet run of up to three hours and no patio hose. The Party Grill 400 at £96.01 names a CV470 Plus, and the title also says an R907 cylinder. All three are cartridge grills. One household’s 400 g canister time is not a rated endurance. The CosmoGrill at £119.99 includes a propane regulator and hose. Reviewers who already had butane said a regulator swap worked. That swap is their report, not a second hose in the box. The George Foreman at £125.00 includes a UK hose, and the UK texts say it does not fit a small screw-on cylinder. The Char-Broil at £157.97 wants a 16.4 ounce disposable propane cylinder, sold separately. The O-Grill titles say dual gas and name no fitting. O-Grill 500 reviews needed a threaded cartridge. The onlyfire does not name a regulator. If the card does not name the valve, you do not yet know what to pack.

Cold weather

Butane fails first when the evening is cold. The Camping and Caravanning Club says liquid butane struggles below about 4°C, and that many cartridges are a propane-butane mix. Calor puts butane’s boiling point near −2°C and propane near −42°C. A CV470 from one UK retailer is described as 450 g, 80% butane and 20% propane. The mix can still work on a cool morning when a pure butane bottle has faded. Water in a Party Grill cartridge well stops the spark even in July, which is a wet piezo, not vaporisation. The camping page covers where you may stand it. Cold weather does not move the cook into the awning.

When a cartridge is the better buy

A cartridge is the better buy when the grill comes out of a boot for a weekend, the meal is one or two people, and you already know the CV clip. The Party Grill at 2.9 kg and £43.92 is that end of the set. The 200 adds stated output at £56.01. The 400 adds the bag at £96.01. A bottle is the better buy when you already pay for patio gas and the grill includes a matching hose. In this set that is the CosmoGrill’s propane regulator, or the George Foreman only after you have checked the hose against your bottle. A 5 kg patio bottle will not clip into a Party Grill. The Char-Broil’s disposable cylinder is neither a CV cartridge nor a refillable Calor bottle.

Common questions

Can I put a Calor bottle on a Party Grill?
Not with the fittings these listings include. The Party Grill, the 200 and the 400 name Campingaz CV cartridges. The 400 title also names an R907 cylinder. None of them lists a 27 mm patio-gas hose. Do not stack adaptors to force the join.
Which grills in this set include a UK hose?
The CosmoGrill includes a propane regulator and hose at £119.99. The George Foreman includes a UK hose at £125.00, and reviews say it does not fit a small screw-on cylinder. The Char-Broil wants a 16.4 ounce disposable propane cylinder, sold separately. The Party Grills are cartridge connections.
Why does butane fade on a cold evening?
Liquid butane stops making useful gas as it gets cold. The Camping and Caravanning Club’s figure is about 4°C. Calor cites a boiling point near −2°C. A CV470 that is mostly butane with some propane can last longer than a pure butane bottle, and it is still the wrong plan for a hard frost.
Does dual gas on the O-Grill name the fitting?
No. Both the O-Grill 500 and the O-Grill 600 say dual gas use in the title and Fuel Type Gas in the specification. The 500’s UK reviews needed a threaded cartridge, and click-and-connect cartridges did not fit. That is a review, on a file of three ratings. Do not treat the title as a diagram.
Is a 16.4 ounce cylinder the same as patio gas?
No. The Char-Broil listing names a portable 16.4 ounce disposable liquid propane cylinder, sold separately. Patio gas, in Calor’s words, is the green propane bottle in 5 kg and 13 kg sizes with a 27 mm clip-on at 37 mbar.
