About O-Rings

The X shape of this Buna-N cord stock provides four points of contact for a better seal in dynamic applications than round profile. It also requires less compression to make a seal, so it offers a longer service life. This cord stock resists hydraulic oils, ethylene glycol, and motor oil.
