Armoured braided gas cooker flexi hoses are covered with galvanised steel braiding, then a white polyolefin cover. Maximum working pressure: 250 p.s.i., or 20 mbar if bayonet type. Temperatures range from: -30 °C to 90 °C; or 70 °C when fitted with polyolefin cover. With bayonet hoses the pressure limit is fixed by the bayonet elbow and socket. The socket is identical to that used on domestic cooker flexi hoses and is designed to operate at a nominal inlet pressure of 20 mbar (0.29 p.s.i.) tested to 50 mbar at a maximum temperature of 95 °C.
