This O-ring kit is sourced from the original manufacturer for use in nailers. The kit includes a set of 12 O-rings in various sizes. The O-rings help to maintain the correct pressure levels by preventing air from leaking out and ensuring the efficient operation of the equipment. Over time they can become brittle, lose their elasticity, or break leading to air leaks and reduced performance. It is recommended to inspect and replace the O-rings as part of the regular maintenance of the equipment. Simply remove the faulty O-ring, clean the mounting surface, and firmly press the new one into place.

Correct parts for needed repair
I needed to replace a broken O-ring on an otherwise excellent tool I had no difficulty finding the parts, they were good quality for a fair price and they arrived promptly. I have consistently four eReplacementParts a reliable company.

Although the problem ended up being the trigger valve assembly needing to be replaced, I thought it would be a good time to replace all the other o-rings in the gun. The cost was under $30 and the instructions were easy. You only need to remove the cylinder cap (4 bolts) and follow the instructions and diagram provided by ereplacement.
