Product Description

?

This is a genuine manufacturer-sourced replacement part which is used in Senco nailers. Its purpose is to distribute the pressure evenly and provide an air-tight seal for the firing valve assembly. Over time seals tend to become brittle and may crack eventually requiring replacement to maintain peak performance. This part is made of durable rubber material and it is sold individually.
