    Know your regulators

    Propane bottles contain considerably greater pressure than butane cylinders. Cylinder regulators designed for use with either propane or butane are not interchangeable because of:

    • Their different design pressure
    • The dissimilar bottle valves for the two gases

    The regulator must be matched to the appliance working pressure and throughout use:

    • High pressure regulators for equipment designed for high pressure (usually 1 bar / 15psi; 0-2 bar / 0-30 psi) propane.
    • Low pressure regulators for equipment designed for low pressure, usually 28mbar (11.2in WG) butane or 37 mbar (14.8in WG) propane.

    Selecting the correct regulator

    To select the correct regulator, check the appliance catalogue or examine the appliance itself. There should be a data plate stating the required throughput and inlet pressure.

    If in doubt, consult the appliance manufacturer or contact us, we’re here to help.

    Fitting of hoses and regulators to gas bottles

    Hoses and regulators should comply with the relevant British and European standards.
    Only 20mm regulators should be used with Flogas blue cylinders, and 21mm regulators with Flogas gold cylinders.

    How to use a gas regulator

    Connect gas bottle regulators with ease with our step-by-step fitting guide.

    Ensure the hose is the right size to fit the regulator nozzle.

    Apply a light coat of soapy water to the regulator nozzle.

    Push the hose firmly over the nozzle completely and tighten the Worm drive (or crimp the O-clip).

    Fit the regulator to the cylinder valve. For propane screw thread connections, ensure the mating threads are clean and undamaged and that the connection is firmly tightened (nipped) with a spanner and ensure they are not cross-threaded. Clip-on propane and butane regulators should be pressed firmly onto the valve so that it locks into position – the regulator must be in the ‘off position’ for the regulator to clip into position.

    Switch on the gas supply. Apply soapy water to the joints.

    If bubbles appear on any of the joints, check the following: the propane screw thread connection may need tightening further or, if threads are damaged, replace the regulator; the Worm screw clip may not be tight enough (you’ll need to tighten it again), or the connection isn’t properly made (just remove the connection and refit).

    All LPG appliances should be serviced regularly by a registered gas installer.
