Amerex Brass Valve Stem for Wheel Units 05067 - OEM

The Amerex 05067 is a genuine OEM brass valve stem for Amerex wheeled fire extinguishers — specifically designed for brass-valved wheeled units including dry chemical, Halon 1211, and Halotron models. The valve stem is the central mechanical component of the discharge valve: when the operating handle is actuated, the stem opens to allow agent discharge, and when released, it helps reseal the valve to stop discharge. A worn, corroded, or damaged valve stem can cause incomplete valve closure, slow actuation, or total valve failure — any of which constitutes an immediate NFPA 10 service deficiency.

Amerex wheeled fire extinguishers are deployed in industrial environments — manufacturing facilities, aircraft hangars, fuel storage areas, and large commercial operations — where their higher agent capacity is needed to fight larger potential fire scenarios. These units experience more demanding service conditions than portable extinguishers, and their valve components are subject to more frequent actuation cycles. The 05067 OEM brass valve stem ensures the wheeled extinguisher valve maintains its full rated discharge performance over multiple service intervals.

The 05067 is listed in the amerex fire extinguisher parts list for compatible wheeled unit models and is available through authorized amerex distributors. The valve stem assembly and valve stem guard components must all be inspected at every 6-year and 12-year internal examination per NFPA 10, with the 05067 replaced if any wear, corrosion, or deformation is found. Document the inspection and any replacement in the fire extinguisher inspection and maintenance tags record.

Internal Examination

During the 6-year and 12-year internal examinations of Amerex wheeled extinguishers per NFPA 10, remove the valve assembly and inspect the 05067 valve stem for corrosion, wear on the seating surface, thread damage, and deformation of the stem pin. Replace the valve stem with a new 05067 OEM part if any defect is found — a compromised valve stem cannot be repaired and must be replaced to maintain the extinguisher's UL listing. Document the inspection and replacement in the fire extinguisher inspection and maintenance tags record.

Post-Discharge Service

After any wheeled extinguisher discharge, the valve assembly must be disassembled and all internal components including the 05067 valve stem inspected before recharge. Discharge forces can deform the valve stem pin or seating surfaces in ways not visible externally. Replace as needed with the OEM 05067 and perform a complete valve rebuild using the correct O-rings and seals before recharging.

Is the 05067 compatible with Amerex portable extinguisher valves?

No. The 05067 is specifically designed for Amerex wheeled extinguisher brass valve assemblies. Portable extinguisher valve stems have different dimensions. Always use the valve stem specified in the amerex fire extinguisher parts list for the specific model being serviced — using the wrong stem can cause valve failure or incomplete agent cutoff after discharge.

Does the wheeled extinguisher valve assembly have a pressure check port?

Some Amerex wheeled extinguisher models include a separate pressure check port on the valve body for verifying the nitrogen charge without discharging the unit. The 05067 valve stem is the main discharge valve component — a distinct part from any pressure check port components. Verify the specific valve configuration for your wheeled extinguisher model using the Amerex fire extinguisher parts list for that unit.
