Running your Buddy heater off a bulk propane cylinder instead of a 1 lb bottle? Mr. Heater recommends adding this fuel filter to catch debris before it reaches the heater, especially when paired with the F273701, F273702, or F298802 hose assemblies.
It attaches directly to the heater and works across the Portable Buddy, Big Buddy, and Tough Buddy lineup, making it an easy add for anyone running a hose-and-cylinder setup instead of disposable bottles.
A low-cost way to protect your heater's regulator when running off a larger propane tank.
