A high-performance industrial component, this Buna-N O-ring features a precise inside diameter of 7.428 inches, an outside diameter of 3.111 inches, and a cross-section of 0.155 inches. The Buna-N (Nitrile Butadiene Rubber) compound offers excellent resistance to oils, fuels, and many hydraulic fluids, making it ideal for dynamic and static sealing applications. The integrated carbon steel core enhances rigidity and compression set resistance, particularly in high-pressure systems. Its material properties ensure durability and longevity in environments requiring chemical inertness and moderate temperature resistance.
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 burrs or damage. 2. Carefully install the O-ring into the groove, avoiding stretching or twisting. 3. Apply a thin layer of compatible lubricant if necessary to facilitate installation and prevent damage.
