Product Summary

Due to contaminants found in propane tanks and propane hose assemblies, it is required for use with all Portable Buddy and Big Buddy Heaters when attaching to a 20 lb. tank. Made of galvanized aluminum, it has 1" – 20 throwaway cylinder threads. Most commonly used with Mr. Heater hose assemblies F273701 (5ft.) and F273702 (12ft.). It measures 3" L x 2" W and is designed to connect to the built in regulator on our Buddy appliances and then to the hose assemblies. It does not connect directly to a propane tank.
