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.

Parts Used
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 from 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 took the nail gun apart to diagnose the problem and identify the faulty part. Then I visited your website and was able to easily find the exploded diagram/schematic for my tool. I ordered the specific parts needed by item number, recieved everything a few days later, and had my nailgun back together in about 10 minutes. Field tested it the next day.
This is not the first time I have orderd parts successfully from your website and being a professional tradesman, it certainly will not be the last. You offer a great service.

J. Chism
