Mr. Heater Buddy Series Hose Assembly 10-ft. - Extend Run Time

In this review the Mr. Heater Buddy Series Hose Assembly 10-ft. is evaluated for users who want to connect a portable Buddy heater to a larger propane supply. The bottom line: this hose is for people who need longer run times without swapping small 1 lb bottles, since the 10 ft. length allows a direct POL connection to 5 to 20 lb tanks and the material design eliminates the need for a fuel filter. For anyone using the MH9B Portable Buddy or MH18B Big Buddy, it solves the frequent bottle-change problem with a simple, secure hookup.

Key Features

• 10 ft. hose length: provides enough reach to position a heater away from the tank and use larger 5 to 20 lb propane cylinders for extended runtime.
• No fuel filter required: the specially designed hose material prevents debris and does not leach oil into the fuel stream, removing the extra maintenance step.
• POL tank connection: attaches directly to standard propane tanks so users can bypass the small 1 lb bottles commonly used with Buddy heaters.
• Secure fittings: both ends tighten securely to prevent leaks and allow a reliable connection to the heater and the tank.
• Compact footprint: measures approximately 3 by 9-7/8 by 11 in, making it easy to store with other camping or garage gear.

Who It's For

The hose is ideal for outdoor hobbyists, contractors, and homeowners who rely on a MH9B Portable Buddy or MH18B Big Buddy heater and want longer, uninterrupted heating periods without changing disposable bottles. It benefits anyone running a heater in a workshop, job site, or campsite who prefers to use larger tanks for convenience and cost efficiency.

Those who should look elsewhere include users with heaters not compatible with Buddy-series 1 lb bottle fittings or people who need a hose shorter than 10 ft. Also, if your setup requires an inline fuel filter for unusual local fuel conditions, double-check compatibility despite the hose's filterless design.
