MEC QCC Connector 1-5/16 in. F-ACME x 1/4 in. MNPT with Excess Flow 200,000 BTU
MEC QCC Connector 1-5/16 in. F-ACME x 1/4 in. MNPT with Excess Flow 200,000 BTU
Item # G1851A

The Type I (QCC) connectors (ME517, ME518 and ME519 Series) are designed with a built-in excess flow 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. To connect a Type I (QCC) connector to a cylinder, close the cylinder valve and the control valves to all connected appliances. Hand tighten the QCC onto the cylinder and slowly open the cylinder valve. If the valve is opened too quickly, the excess ow device will be activated closing the ow of propane to the appliance. If the excess flow device is activated, close appliance control valves and wait 60-seconds to allow pressure in the line to equalize. Additional equalization time may be needed depending on the length of the hose. Turn on appliances by following the manufacturers suggested lighting procedures.

  • Note: the type I (QCC) thread replaces the POL connection on 40 lbs. or less DOT propane cylinders
  • Inlet: 1-5/16 in. female acme
  • Outlet: 1/4 in. MNPT
  • Flow capacity: 100 SCFH air/200,000 BTUH
