MEC 1-5/16 in. F.Acme QCC Evacuation Coupling, Full Flow

The Type I (QCC) connectors (ME517, ME518 and ME519 Series) are designed with a built-in excess ow feature and a positive shutoff that will not allow gas to ow until the connector is fully engaged. In case of a fire the built-in thermal protection on the QCC connector melts allowing the nipple to disengage from the tank connection and stop the ow of propane. These QCC connectors also provide a positive back check seal at disconnect to eliminate the propane in the hose from being released into the atmosphere.|Inlet: 1-5/16 in. female acme|Flow capacity: full flow|Handwheel color: black|Thermal protection: yes|Type: evacuation coupling|UL Listed
