These O-rings are harder and stronger than standard polyurethane O-rings to handle high-pressure applications. They resist mineral oil, motor oil, grease, hydraulic oils, and synthetic lubricants. All have a round profile and are suitable for a wide range of static and dynamic sealing applications. These O-rings are sized to the SAE standard AS568.
Polyurethane rubber is a thermoplastic elastomer formed by reacting a polyol with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Polyurethane rubber is widely used due to its high strength, and excellent tear and abrasion resistance. Polyurethane also provides excellent permeation resistance.
