The Type I (QCC) connectors are designed with a built-in excess flow feature and a positive shut-off that will not allow gas to flow until the connector is fully engaged. In the case of a fire the built-in thermal protection on the QCC connector melts allowing the nipple to disengage for the tank connection and stop the flow of propane. The QCC connector also provides a positive back check seal at disconnect to eliminate the propane in the hose from being released into the atmosphere.
