226 Silicone O-Ring, 70A Durometer, Red, 2 ID, 2-1/4 OD, 1/8 Width (Pack Of 10): O Ring Seals

It has good resistance to ozone, weather, detergent, salt water, engine and transmission oil, non-petroleum brake fluid, hydraulic fluids that resist fire, vegetable and animal oils, and high molecular weight chlorinated aromatic hydrocarbons. Silicone is vulnerable to mechanical wear and tear, water and steam over 250 degrees F (121 degrees C), aromatic hydrocarbons (benzene), chlorinated hydrocarbons (trichloroethylene), acids and bases, and hydrocarbon fuels. O-rings commonly provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in engines, faucets, flanges, valves, and various cylinders. O-rings are available in a number of sizes, and can be ordered based on required nominal inside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter. A higher durometer value indicates greater resistance to indentation on a scale of 0 to 100, with 100 indicating no indentation. This silicone O-ring meets standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings. Made of silicone for use with a variety of chemicals and fluids Can be used across a wide temperature range from -65 degrees F (-54 degrees C) to 450 degrees F (232 degrees C) Round in cross-section to provide a seal between cylindrical overlapping surfaces Durometer (hardness) of 70A for resistance to penetration Meets standards defined by Aerospace Standard AS568A
