Connect and disconnect moveable equipment with the Dormont A75R 3/4 inch SnapFast Quick Disconnect Coupler. Features a polymer ring, used as a thermal shutoff feature, located inside the nipple that melts and closes the gas supply valve if temperature rises above 350F. The push-to-connect feature allows coupling's components to be joined quickly by pushing and snapping into place. No need to hold or slide the operating ring.
