Also known as Quattro Seals and X-rings, these X-profile O-rings have four points of contact for a better seal in dynamic applications than round-profile O-rings. They also require less compression to make a seal, so they offer a longer service life. These O-rings are made of Buna-N, which is resilient and tear resistant. They resist motor oil. These O-rings are sized to the SAE standard AS568.
