O-rings are made to contain thousands of PSI pressure by creating a seal between two or more parts. O-ring measurements are specified by the inside diameter and the thickness. Of the many causes for O-Ring failure, the most common among power tools are: • <u>Extrusion and Nibbling</u> - O-ring has ragged, tattered edges. These are commonly caused by pressure spikes which shear off tiny "bites" from the o-ring, or caused by clearance gaps. • <u>Abrasion</u> - One or both sides of the o-ring appear rough and slightly flattened. Commonly caused by a contact surface that is too rough, contains grit or is too smooth to allow lubrication. • <u>Over Compression </u> - O-ring is flattened on both sides and may have a "ring" split along its length. Commonly caused by excessive pressure or heat. • <u>Heat Hardening</u> - O-ring has a pitted or cracked surface, and often is flattened on both sides. Caused by temperature exceeding o-ring capacity. • <u>Weather/Ozone Cracking</u> - O-ring is covered in small surface cracks. Caused by exposure to ozone, UV rays and air pollution. Excessive seal stretching causes similar cracking.

Excellent service!
The parts I received were the ones I ordered and were in great condition. I ordered one part I did not need and the return process was EASY. Parts are easy to find and identify on the website. Thankful to be able to find parts for my older tool. My nail gun is back in action and projects are being accomplished again.

Everyone said top bumper causes the problem. The bumper was shot so I replaced it. Still did the same thing. Messing with it I found that if I pulled on the trigger pin just a little bit it would let go and retract the driver. I pulled the trigger assembly out and started messing around with it. No luck. However I now noticed a slight air
