21 mm Clip on Butane Regulator
£16.00
This 21mm clip-on butane regulator is the standard fitting for portable butane heaters. It clips straight onto a 21mm valve by hand, with no tools, and an on/off lever lets you see at a glance whether the gas is open or shut.
It’s a low pressure regulator, so it sits between a butane cylinder and the heater and brings the gas down to the working pressure the appliance needs. It’s the right match for Calor butane bottles used with portable heaters, such as the 7kg and 15kg.
Always check the regulator suits your cylinder valve and appliance before use, and follow Calor’s guidance on fitting. We deliver across our defined Reading area, so check your postcode is covered, or call the yard on 0118 9242888 if you’re not sure what you need.

The 21mm clip-on butane regulator is the everyday fitting for portable indoor butane heaters. It clips onto a 21mm cylinder valve by hand, so there are no tools and no threads to line up, and the on/off lever gives you a clear, simple way to shut the gas off or open it up.
As a low pressure regulator, its job is to step the butane down from cylinder pressure to the working pressure the heater needs. That makes it the standard partner for Calor butane cylinders used with portable heaters, such as the 7kg and 15kg bottles. If your appliance specifies a different connection or pressure, it won’t be the right part, so check before you buy.
Fitting should follow Calor’s own guidance, and any doubt about the right regulator is worth a quick call rather than a guess.
