Abstract: An end fitting for use in connecting a gas source in fluid communication to an appliance, includes a nut mounted by a fusible and meltable heat activatable material on a socket having a chamber for receiving a plug. The plug connects to the gas source and the socket connects to the appliance. An O-ring of meltable heat activatable material separates the plug and socket. The socket includes a spring that biases a valve member against the plug and between closed and open conditions, respectively, to block or permit fluid flow from a source and through the chamber. In case of excess heat buildup in the socket body, the heat activatable materials melt but unless the gas source is turned off always allow a predetermined amount of gas to flow.
