Seals and cover
I also ordered seals for my nailer. Site had a diagram of nailer and exactly what I needed. This was the second time I used them. Highly recommend.

Always Great Customer Service
This last order was a no brainer - ordered, shipped installed, nothing out of the ordinary. But that is true for everything I have ordered, obscure component or regular replacement. Always great customer service. Thank You.

Old Nailer Restored!
Easy reference charts to identify the broken parts and the installation process. Simple replacement restored my old pneumatic brad gun! Easy order and prompt delivery! I love being able to restore rather than to replace! Thanks for making this possible!

Disassembled nailer and found all the nylon seals crumbled. (It’s 40 years old). O-rings were good. Cleaned all parts with electronics cleaner and compressed air. Replaced two nylon seals (and the spring I lost). Lubed, reassembled and it was a win.
