Abstract
A coupling for connecting a cylinder valve on an LPG tank to the inlet of a pressure regulator for gas consuming equipment comprises a nipple having an upstream end for connection with the cylinder valve and a downstream end for connection with the pressure regulator, and a plastic coupling nut for connecting the nipple to the cylinder valve. The end wall of the coupling nut has a metal heat transfer washer on the inner side thereof, and a pressure responsive flexible shutoff valve plate is provided in the nipple passageway. The shutoff valve plate closes the passageway in response to a pressure differential thereacross of no more than 15 psi, and the end wall of the coupling nut and the heat transfer washer are responsive to a temperature of between 240° F. and 300° F. to release the nipple for displacement away from the cylinder valve in the direction downstream of the nipple.
