Propane gas regulator, used to deliver a steady supply of gas to a single appliance which connects to the bottle. The inlet connects to the propane supply, where pressure can fluctuate, and ensures that excessive gas pressure is not delivered which could cause damage. The regulator works by setting the outlet pressure lower than the inlet pressure, and is suitable for use with propane 37P gas. It is vital that all gas installations are checked by a qualified gas engineer prior to use to ensure safety on board. Please Note: This gas regulator is only recommended for use in fresh water installations - it is NOT manufactured to marine standards. Please see our range of GasBOAT regulators for gas equipment that are approved (ISO 10239:2014 and BS EN 16129 M 2013) for use in all marine installations.
