This silicone O-ring is red in color, round in shape, has a durometer of 50, and is designed for use in a wide variety of sealing applications. 2. This silicone O-ring can be used across a wide temperature range from -22℉ (-30℃) to 392℉ (200℃) 3. O-rings commonly provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in faucets, flanges, valves, and various cylinders. 4. This silicone O-ring has good resistance to ozone, weather, salt water, non-petroleum brake fluid, hydraulic fluids that resist fire, vegetable and animal oils, and high molecular weight chlorinated aromatic hydrocarbons. It is a great solution for sealing application where there are high temperatures and corrosive liquids or gases involved. 5. Used widely for mechanical sealing, pressure , gas compressor, reaction, heat exchanger, boiler, filter, electrical appliance and other fields.
