Product Description

This is a genuine head valve for nailers and staplers. The head valve is responsible for controlling the flow of air to the cylinder. When the trigger is pulled, it creates an imbalance of pressure, which opens the head valve and fires the piston. The head valve is prone to wear over time, so it is important to inspect it often. The seals on the head valve or the body itself can begin to harden and eventually crack, and this results in air leaking from the gun exhaust. For this repair you will need an Allen wrench adjustable wrench and a screwdriver. This plastic head valve is sold individually.
