This is a manufacturer sourced replacement part designed for use with Chicago Pneumatic ratchet/wrenchs. This o-ring provides an air-tight seal for the valve. Over time this o-ring will shrink, become brittle and crack allowing for air leaks. At that time it should be replaced. It is made out of rubber and it is sold individually. Replacing this item you would need hex key/allen wrench and pliers to replace this item.

The valve throttle in my 3/8 inch air ratchet wrench disintegrated after sitting for an extensive period of time.
Removed plug with the screwdriver. Replaced valve-throttle, O-ring, and plug. Lubricated the wrench with air tool lubricant. Worked perfectly. Straight forward repair using the diagram on the website. No issues.
Replaced plug throttle valve only a couple parts in there. It is a 20 year old CP air ratchet I was surprised you had parts for it. Easy cheep fix. I will always check eReplacementParts first.
1. unscrew cap.
2. pull spring and debris.
