344 Silicone O-Ring, 70A Durometer, Red, 3-7/8' ID, 4-1/4' OD, 3/16' Width (Pack of 5): O Ring Seals: Industrial & Scientific. 344 Silicone O-Ring, 70A Durometer, Red, 3-7/8" ID, 4-1/4" OD, 3/16" Width (Pack of 5): O Ring Seals: Industrial & Scientific. This silicone O-ring is red in color, round in shape, has a durometer of 7OA, and is designed for use in a wide variety of sealing applications.。 Silicone is acceptable for temperature applications between -6 degrees F (- degrees C) to 0 degrees F (232 degrees C). 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 20 degrees F (2 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. They are circular in shape, with a round cross section and a hole in the center, similar to a doughnut. 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. 。 This silicone O-ring has a shore durometer of 70A. Shore durometer is the hardness of a material, and its resistance to permanent indentation. A higher durometer value indicates greater resistance to indentation on a scale of 0 to 00, with 00 indicating no indentation. 。 This silicone O-ring meets standards defined by Aerospace Standard AS6A, which is the Aerospace Size Standard for O-rings.。。。。
