Manufactured under strict quality controls, this Buna-N O-ring is engineered for exceptional sealing performance. With an inside diameter of 3.913 inches, an outside diameter of 6.199 inches, and a precise 0.241-inch cross-section, it's designed for tight tolerances. The Buna-N material offers excellent resistance to oils, fuels, and many hydraulic fluids, making it suitable for a wide range of industrial applications. The integrated carbon steel provides enhanced structural integrity and rigidity, crucial for high-pressure or high-vibration scenarios where standard elastomers may fail. It's ideal for static and dynamic sealing applications in pumps, valves, and hydraulic systems.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the sealing groove is clean, dry, and free from debris. 2. Lightly lubricate the O-ring with a compatible lubricant (refer to material compatibility charts). 3. Carefully install the O-ring into the groove, avoiding any stretching or twisting.
