Includes Nitrile Butadiene O-Rings and one 90 durometer Polyurethane piston o-ring. The piston o-ring is the most crucial seal in the pump, and the one that faces the highest stress and abrasion. Black buna o-rings often fail prematurely in this application due to the high heat and abrasion faced when pumping the piston. The polyurethane piston o-ring ensures lasting performance of this critical o-ring.

This item includes a full rebuild of O-Rings (as pictured) in a resealable zip-top poly bag with "Captain O-Ring" branded packaging.
