Zefal Piston Rubber Washer

Out of stock.

Product Overview

Zefal's HPX frame pumps are legendary for their reliability but they do have a couple of parts that are subject to wear.  This 18mm rubber seal replaces the piston washer that holds air pressure as you inflate your tires and will fix that old, leaky pump of yours.  Apply a light coat of grease and you're good to go. 

We also carry the pump head rebuild kits for HPX pumps
