Built to exacting engineering tolerances, this Buna-N O-ring boasts an Inside Diameter of 2.828 inches, an Outside Diameter of 2.558 inches, and a Cross Section of 0.243 inches. The Buna-N (Nitrile Butadiene Rubber) material provides excellent resistance to oils, fuels, and many hydraulic fluids, making it suitable for a wide range of operational temperatures. The brass core offers superior dimensional stability and chemical inertness in specific corrosive media, while also providing grounding capabilities where required. Its precise dimensions ensure a secure and leak-free seal within appropriate groove configurations.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating groove surfaces are clean, dry, and free from burrs or defects. 2. Carefully place the O-ring into the designated groove, avoiding excessive stretching or twisting. 3. Assemble the mating component, ensuring even pressure distribution across the O-ring's surface.
