This is a 12 ft. hose with a built in regulator that will connect the Mr. Heater Big Buddy to a twenty pound propane tank. The regulator on this hose allows the hose to bypass the regulator in the Big Buddy by connecting to the quick-disconnect fitting on the Big Buddy instead of the screw-in connection. This hose gives you 1/2 PSI through the hose at any given time instead of 100 PSI that other hoses provide. This provides much safer conditions should a leak in your hose occur.
