Primus Expedition Replacement Hose with Valve for MultiFuel, OmniLite, EasyFuel and OmniFuel Stoves

The Primus Expedition Hose with Valve (part number P731930) is a replacement hose-and-valve assembly compatible with Primus MultiFuel, OmniFuel, OmniLite, and EasyFuel stoves, specifically models 3219, 3277, 3288, and 3289. It is designed to restore a worn or damaged fuel line so the stove can return to service rather than be retired.

Repair Instead of Replace

The hose and valve are among the highest-wear components on a multi-fuel expedition stove. A cracked hose or a valve that no longer seats cleanly means the stove cannot pressurize reliably, which matters most when conditions are already difficult. Swapping this assembly restores the fuel path without requiring a new stove, which keeps a proven piece of kit in rotation and avoids the cost and break-in time of a replacement unit.

Designed for Field Serviceability

Primus designs its expedition stoves so that owners can perform their own service. This hose-and-valve assembly is a discrete, user-replaceable part rather than something bonded into the stove body, which means the repair can be done at home or in camp without sending the stove to a service center. Keeping a spare on hand before a long trip costs little and removes a single point of failure from a critical piece of gear.

What is included with this part?

The Primus Expedition Hose with Valve ships as a single assembly containing the hose and the valve together. No stove, fuel canister, or additional hardware is included.

Can this repair be done without sending the stove to a service center?

Primus designs its expedition stoves for owner serviceability, and this hose-and-valve assembly is a user-replaceable part. The repair does not require a service center visit, though following Primus service documentation for the specific stove model is recommended before beginning the replacement.

How do I know if the hose or valve on my stove needs replacing?

Common signs that the hose-and-valve assembly on a Primus expedition stove needs attention include visible cracking or stiffening of the hose, fuel odor when the stove is pressurized but not lit, or a valve that no longer holds pressure consistently. Replacing the assembly at the first sign of wear is safer than continuing to use a compromised fuel line.
