Product Overview

Designed to provide a safe permanent outlet when installed into the household LP-Gas system. This permanent outlet eliminates the need for smaller containers when operating outdoor LP-Gas equipment. It is recommended that a shutoff valve be installed upstream from the adapter inlet to facilitate future servicing.

  • Can be used with both type I (QCC) and male Pol connections
  • Includes an internal shutoff valve which provides a leak free means for outdoor equipment to be safely connected and disconnected without shutting down the entire system
  • Inlet: 1/4 in. MNPT
  • Outlet: 1-5/16 in. male Acme/female Pol
  • Quick closing
  • Warning: an excess ow valve will not activate if there is a break or leak downstream of the valve that does not equal or exceed the closing ow of the valve or if the excess ow valve installed exceeds the ow capacity of the system, see the excess flow warning page for more information regarding the use of excess ow devices
