Genuine Bostitch replacement part, this item is sold individually.
There are two of these gaskets used on the compressor models shown below.
They are placed in between the AB-A640050 Valve Plate Assembly.
The purpose of the gaskets is to create a seal so air will not leak out.
Over time these will wear and have to be replaced.

This would be a good time to inspect the Valve plate Assembly for wear also.

During my basement remodel, my Bostitch air compressor quit building up pressure. It sat idile for 3 years. Bought another inexpensive compressor but ccouldn\
Simple repair. Removed the cover. Removed air tube from compressor head. Removed 4 head bolts. Removed the head, valve plate assembly and gaskets on both sides of the valve plate. Reassembled in reverse order. was fast in shipping the parts and was over half as expensive as other places. Second time I used them and will continue to with next project.
