Type 1 (QCC) Appliance Connectors

The Type 1 (QCC) connectors (ME517, ME518 and ME519 Series) are designed with a built-in excess flow feature and a positive shuklff that will not allow gas to flow until the connector is fully engaged. In case of a fire the built-in thermal protection on the QCC connector melts away allowing the nipple to disengage from the tank connection and stop the flow of propane.
