What Are Gas Bottle Adaptors?
A gas bottle adaptor is a fitting that connects a gas cylinder valve to a regulator or appliance when the connection types differ. They are commonly used for:
-
Caravans and motorhomes – linking clip-on type gas bottles to caravan regulators.
-
Outdoor cooking and heating appliances – connecting cylinders to barbecues, patio heaters, or portable stoves.
-
General LPG applications – allowing safe conversion between different cylinder outlet types.
By ensuring a secure connection, adaptors prevent leaks and maintain a consistent gas flow, keeping your installation both safe and efficient.
Our Range Of Gas Bottle Adaptors
BES supplies a carefully chosen range of adaptors to cover the most common requirements for butane and propane gas bottles, with each adaptor being engineered for durability and ease of use, ensuring a long service life and secure performance.
21mm Clip-On Adaptors
Designed for butane bottles, these adaptors allow quick and secure connection to caravan regulators or small appliances. Options include standard 21mm clip-on fittings and models with 21.8 LH threaded outlets.
27mm Clip-On Adaptors
Our range of 27mm clip-on adaptors is suitable for propane gas bottles, offering a reliable fit for caravan regulators and other LPG applications. Available in both straight and angled versions to accommodate different installation setups.
Choosing The Right Gas Bottle Adaptor
When selecting an adaptor, consider:
-
Gas Type – 21mm adaptors are generally for butane bottles, while 27mm adaptors are for propane.
-
Connection Type – Clip-on to threaded (21.8 LH) adaptors allow you to connect bottles to regulators with differing outlet types.
-
Installation Space – Angled adaptors are useful in confined spaces where a straight connection may not fit.
-
Regulator Compatibility – Always match your adaptor to the regulator being used to ensure a safe, leak-free fit.
If in doubt, our team can help you identify the correct adaptor for your cylinder and appliance setup. Just give us a call and we would be happy to help.
Safety Guidance For Gas Bottle Adaptors
-
Always ensure the adaptor is compatible with both the bottle and regulator before use.
-
Never force connections – a proper fit should be secure without over-tightening.
-
Inspect seals and fittings regularly for signs of wear or damage.
-
Only use adaptors for their intended gas type (butane or propane).
-
For caravans and motorhomes, installations should comply with UK LPG safety regulations and be checked regularly by a Gas Safe registered engineer.

Gas Bottle Adaptors FAQs
What is a gas bottle adaptor used for?
A gas bottle adaptor allows you to connect a cylinder with one type of valve fitting (e.g., 21mm clip-on) to a regulator or appliance that requires a different connection type.
What is the difference between 21mm and 27mm adaptors?
21mm adaptors are designed for butane bottles, while 27mm adaptors are for propane cylinders. Using the correct size ensures a safe and secure fit.
Can I use a gas bottle adaptor on a caravan regulator?
Yes. Our adaptors are designed to connect clip-on bottles safely to caravan regulators.
Do I need a straight or angled adaptor?
Straight adaptors are standard, but if space is tight or pipework prevents a direct connection, an angled adaptor provides more flexibility.
Are BES gas bottle adaptors compatible with all regulators?
Our adaptors fit most standard UK regulators, but always check the thread type and size before ordering. If unsure, contact our team for advice.
Are there safety regulations for using gas bottle adaptors?
Yes. Always use the correct adaptor for the cylinder and regulator type, and ensure installations meet UK LPG safety standards. For caravans and motorhomes, fittings should be inspected regularly by a qualified engineer.
