Propane cylinders possess higher pressures than butane gas cylinders. Cylinder regulators are designed to work independently as the valves are dissimilar. High pressure gas regulators are designed for 1 bar or 15 psi (pounds per square inch) or 2 bars (30 pounds per square inch) Low pressure propane regulators can handle gas pressures of 37 mbar. It is important to understand the ratings of the regulators as affixing a low pressure regulator for a high pressure installation will not allow the device to function properly.
Hose fitting to the regulator
British and European gas regulation standards mandate that regulators and hoses comply with updated regulations. For instance blue coloured cylinders should use 20 mm regulators while gold coloured cylinders should use 21 mm regulators. The hose should fit tightly to the regulator. The correct procedure of fitting the hose to the regulator is making use of a soapy liquid solution coating the nozzle of the regulator and then firmly pushing the hose to the end of the nozzle. Worm clip is then tightened or crimp-o-clip is also used to fasten the hose to the regulator tightly. The regulator is then fit over the gas cylinder valve. The gas supply is switched on by activating the lever on the regulator to the ON position. Soap solution is then dripped lightly on the connection joint. If soap bubbles are formed it is indicative of gas leak. Retighten the worm clip and check again for leaks.
It is assumed that the high pressure gas regulator for propane and hose assembly is in compliance with British standards. To ensure that this condition is met it is important to source gas equipment products from a trusted and dependable source such as Gas Equipment Direct. They are in the business of distributing gas components for nearly three decades.
