Product Description

?

Genuine Chicago Pneumatic replacement part, this item is sold individually. This part acts as as a seal so that air will not leak out of the throttle assembly on the tools shown below. Over time it will become brittle and crack. It is a good Idea to keep an extra one on hand.
