This is a genuine manufacturer sourced replacement part designed for Bostitch staplers. This gasket provides an air-tight seal for the spacer cap. Over time this gasket will shrink, become brittle and crack allowing for air leaks. At that time it should be replaced. It is made out of compound material and it is sold individually.
Replacing this item you would need pliers.
