This is an OEM replacement O-ring for a nailer, sold individually. This O-ring is what seals the cylinder to the housing of the gun and creates separation between the upper and lower air chambers. Due to its rubber material, over time, it can wear. For this repair you will need to remove the cap, disassemble the head valve, remove the spring, and remove the old O-ring. Apply some lubrication to the new O-ring and place it on the valve.

This is an individually sold cylinder seal for a nailer. As the name describes, it is placed on the cylinder of the nailer. It prevents air from leaking from inside the tool. Like all seals, it can become fragile, stretch, and break over time. If your tool requires a complete rebuild of all gaskets, seals, and O-rings, a rebuild kit is sold separately. This seal has an approximate outer diameter of 2-9/16-inches and an inner diameter of 2-15/16-inches.

This part includes one OEM O-ring for a nailer. The O-ring creates an air-tight seal around the piston stem. When O-rings fail this will hinder the performance of the nailer and may prevent the driver from returning. Since you will need to disassemble the nailer to access this O-ring, it is also a good idea to inspect all O-rings and replace them as well. If one is failing, it is likely that the others will be soon to follow. You may require some grease when installing your new O-ring.
