Detailed Engineering Specifications

Built to exacting engineering tolerances, this Buna-N O-ring features a precise 6.576" inside diameter, 1.137" outside diameter, and a 0.175" cross-section. The robust Buna-N (Nitrile Butadiene Rubber) material offers excellent resistance to oils, fuels, and hydraulic fluids, while the integrated nylon provides increased tensile strength and improved wear characteristics. This combination ensures a reliable seal in high-pressure systems and environments prone to abrasion, maintaining its sealing integrity over a wide temperature range. Its Shore A hardness of 70 Durometer ensures optimal compression for a leak-proof fit.
