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.

Porter cable brad nailer.
Was not the part need. Website was misleading on part needEd. Went and bought a harbour freight Brad nailer for $9.00 more than the parts and shipping.

Removed Allen screws...need good hardened steel wrenches...removed and replaced o rings and seal...did not replace piston o-ring. Greased and reassembled. (Used white lithium grease). Tightened well... ..still leaked a tad.....fired one nail and leak stopped. Guess the o- rings needed to seal.
