These O-rings are made of Buna N for use with gasoline (up to 15% ethanol content), ATF, and oil. They are designed to seal standard (SAE) O-ring ports. The female port must be chamfered to provide a reliable seal. For flat ports, try our Aluminum Stat-O-Seals (Part No. 3245). Temperature range -30° F to 250° F (-34° C to 121° C).
