This is a manufacturer sourced replacement part. This seal is used on Porter Cable nailers/staplers. This seal plays an important role because it helps to provide and air tight seal for the piston. Over time it will shrink, become brittle and crack allowing for air leaks. Replacing it should resolve the issue. It is a good idea to check other seals and gaskets in a tool when replacing one seal. It is made out of rubber material and it is sold individually.
Replacing this item you would need hex key/allen wrench.

I removed the top cap of the stapler by removing four screws. I then notice that the seal was broken up. I then proceeded to completely clean out all of the debris out of the stapler. Oil the o-rings and seals , then installed the new the seal. Then installed the top cap back one the stapler. I test fired it, and it worked like a champ.
