Double X-Profile Oil-Resistant Buna-N O-Rings
These O-rings have eight points of contact for a better seal in dynamic applications than X-profile O-rings, plus they have eight grooves that hold lubricant to reduce friction and wear for a longer service life. They’re made of Buna-N, which is resilient and offers excellent tear resistance. These O-rings resist grease, hydraulic oils, and motor oil. They're sized to the SAE standard AS568.
