Product Description

?

It is a genuine item that is supplied by the original equipment manufacturer for use with Bostitch and Porter Cable pneumatic nailers. O-rings are generally utilized to provide a tight seal between connected components. Unfortunately, over time it will wear out and may begin to crack eventually requiring a replacement to maintain the proper seal. Make sure to check the owners manual and the appropriate diagrams of your model for the exact location and application of this part. Keep in mind this high-quality o-ring is made of durable rubber and is sold individually.

Actually went very smooth. Had slight air leak on the first attempt, used a little silicone on the second and have not looked back since. Your service including shipping was about 20% of a normal repair bill. Will use again.
