This OEM part is used in assorted nailers and other tools manufactured by Bostitch. An O-ring is a flexible piece which seals and protects between rigid parts in order to maintain correct pressure. Many machines use more than one type of O-ring throughout. Consult manual to use the right O-ring in the right spot. This part is sold individually.
I removed gun head and saw the problem. Removed piston with a 90 degree pic through center of piston. I then prepped new piston by installing new o-ring, piston spring, and lube. I then pressed piston assembly into gun head, installed gun head with four screws. Test fired worked perfect.
Remove top of nailer, there are 4 Allen screws. Once removed in top piece that was removed there is one more small Allen screw to remove on the outside. Once removed the piston head valve comes outGǪclean the are, install new piston head valve and o rings, reassemble.

Bostitch n75c siding nailer started shooting the piston out when I connected it to air.
I removed the back section of the gun behind the trigger using an allen wrench set.
I looked inside and noticed the white collar was cracked.
I removed the piece by pushing out from the outside of the gun where the air vents.
Ordered the replacement part.
Parts came and I reassembled from the diagram on the website
