This is a genuine manufacturer approved replacement o-ring used on Porter Cable nailers/staplers. O-rings are designed to withstand high pressure by creating a seal between two connected parts. Over time o-rings will damage and should be inspected periodically. If parts are showing signs of wear they should be replaced. This is a rubber o-ring and it is sold individually.

Exact fit and easy to install, this o-ring stopped the air leak on my P/C stapler. Parts are going to age and wear and it’s good to be able to get replacements.
Came well packaged in the mail with no issues.

P-C brad nailer (BN200 Type 1) would not reset the plunger,
P-C brad nailer (BN200 Type 1) would not reset the nail plunger, the o-ring was part of the problem.
1. Removed the black top of nail gun using supplied Allen/hex tool.
2. Removed valve disk with damaged clear/white o-ring. It is either on the nail plunger or in the black top.
3. Valve spring was clogged with debris
... Read morefrom failed o-ring, cleaned and re-seated.
4. This did not solve problem, disassembled unit again, cleaned exit air vent (on the black nailer top, with a toothpick and compressed air also cleaned the air path under valve disk. Seemed the exit air vent had debris and dust/gum build up from using pneumatic oil.
5. Reassembled and did limited testing. More testing to follow. So far so good.
6. While it took 2 hours, if I did the full cleaning the first time - the entire repair would have been less than 30 minutes.
I broke nailer down completely and reinstalled all new parts..You make it very easy for repair..All your parts are clearly marked for ease of replacement..Thanks for all you do..Rich Lincoln Ca
I took the unit apart at the cylinder and replaced an O ring . The repair was easy. The piston came apart just after unscrewing four screws.
The item that I replaced was not enough to make the nailer work and I chose to forgo any further repairs. I purchased a new nailer.
1. Remove top cap from Porter Cable BN125 brad nailer by removing four allen screws.
2. Clean interior thoroughly.
3. Install part #103 o-ring and part # 104 seal.
4. Re-assemble and replace top cap and four allen screws,
