What a great place. Easy to use website, was able to quickly identify the part I needed, only took a couple of minutes to place order, and faster than ever the part was delivered. Fixed my framing gun for $15 and saved myself hundreds of dollars! Will definitely use this company again.

1 - Loosen the 4 Allen head screws from nailer head. It is slightly spring loaded so if your gasket is holding the head you may want to break the seal before completely removing the 4 allen head screws.
2 - Remove the old cylinder seal. Clean out any debris.
3 - Clean the nailer body and head mating surfaces for the new gasket.
4 - Put a few drops on oil on the new seal to help it snap into place without damage.
5 - Re-install the head with the new gasket. Tighten the allen screws using a typical "star" pattern.

The nailer was leaking air and would not drive a nail.

Tools Used
Screwdriver, Scotch-brite to clean the piston area.
I had a o-ring seal kit on the shelf. I found the old seal stuck and gunked up. I had to use scotch-brite to clean that surface before installing the new o-rings
For some reason I did not have a piston stop and I don't know how this nailer ever worked without it? After cleaning everything up, lubricating and installing all the parts, the nailer worked fine.
