The Global O-Ring AS568-008 is a high-quality Nitrile (Buna-N) O-ring engineered for reliable sealing in both static and dynamic applications. Its round design allows it to compress within a groove, creating a secure, leak-proof seal between two or more parts. Crafted from 70 Durometer Nitrile, this black O-ring offers excellent resistance to wear, compression set, and chemical exposure. Its precise dimensions—cross-section 0.07 in, inner diameter 0.176 in, and outer diameter 0.316 in—provide a secure fit for a variety of industrial and mechanical applications. Ideal for use in hydraulic systems, pumps, valves, and rotating shafts, the AS568-008 O-ring ensures dependable sealing under low- and high-pressure conditions. It is compatible with a wide range of fluids, including petroleum-based oils, fuels, aliphatic hydrocarbons, vegetable oils, silicone greases, ethylene glycol, and dilute acids, and maintains performance at temperatures up to 250°F (121°C).
