This 1 in. ID push-to-connect quick disconnect coupling is designed specifically to connect and disconnect moveable equipment used in the foodservice industry. This coupling contains a thermal shutoff feature which is a polymer ring located inside the nipple that will melt and close the gas supply valve if the temperature rises above 350??F. The push-to-connect feature allows the coupling's components to be joined quickly by simply pushing them together until they snap into place, eliminating the need to hold or slide the operating ring.
