Mr.heater 10' Buddy Series - Hose Assembly

The Mr.Heater 10' Buddy Series Hose Assembly (F273704) is a critical connection component designed for users who rely on portable propane heating solutions in garages, workshops, job sites, and off-grid environments. As a mechanic or automotive enthusiast working in unheated spaces, you understand the frustration of numb fingers and sluggish diagnostics in cold conditions—this hose assembly solves that problem by extending your Mr.Heater unit's reach and delivering consistent propane flow to where you need warmth most. Built to bridge the gap between standard 1 lb. throwaway propane cylinders and your heating appliance, this assembly eliminates the need for mounting the heater directly adjacent to your fuel source.

This hose assembly features a 10-foot reach with a swivel 1-20" male throwaway cylinder thread connection on one end and a soft nose excess flow positive outlet load (P.O.L.) fitting with hand wheel on the appliance side. The swivel design prevents kinking and twisting during installation and repositioning, while the excess flow mechanism acts as a safety valve—automatically shutting off propane flow if the connection is compromised or disconnected. The hand wheel allows you to manually throttle propane delivery with precision, giving you control over heat output without touching the main heater unit. This construction ensures reliable, repeatable connections and safe operation in demanding automotive and workshop environments.

Mechanics, fabricators, and DIY automotive enthusiasts benefit most from this assembly when setting up mobile heating stations in their shop or bringing portable heat to job sites. The 10-foot length accommodates flexible placement of your propane cylinder—whether mounted to a wall, stored in a cabinet, or kept at a safe distance—while the hose remains protected from traffic and abrasion. Installation is straightforward: thread the cylinder end onto any standard 1 lb. throwaway bottle, then connect the P.O.L. fitting to your Mr.Heater Buddy Series unit using the hand wheel to secure the connection. This assembly is compatible with all Mr.Heater Buddy Series propane heaters designed for 1 lb. cylinder operation, making it an essential accessory for expanding the practicality of your heating setup.
