Makita 322993-4 Trigger Valve Stem

Product Description

The MAKITA 322993-4 is a replacement trigger valve stem designed for use in Makita pneumatic and power equipment. The trigger valve stem is an internal component that controls airflow or fluid passage through the trigger mechanism, allowing the operator to engage and disengage the tool's function with each pull. This part is a direct OEM-spec replacement intended for service technicians and repair professionals who maintain Makita equipment in the field or at the bench. Replacing a worn or damaged valve stem restores proper trigger response and helps maintain safe, reliable tool operation.

The 322993-4 trigger valve stem is a service part suited for repair and maintenance applications. It is typically installed during trigger assembly overhauls or when the existing valve stem shows signs of wear, cracking, or failure to seal properly. Technicians servicing pneumatic nailers, staplers, or similar Makita tools will encounter this component as part of routine trigger mechanism repair.
