This 3/4 in ID push-to-connect quick-disconnect coupling. The quick-disconnect 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 deg F. This quick-disconnect also features a push-to-connect feature which allows the coupling's components to be joined quickly by simply pushing them together until they snap into place. There is no need to hold or slide the operating ring.
