Specified by design engineers worldwide, this industrial O-ring features a 2.918-inch inside diameter, a 4.908-inch outside diameter, and a 0.154-inch cross-section. The Buna-N (Nitrile Butadiene Rubber) material offers excellent resistance to oils, fuels, and hydraulic fluids, while the integrated carbon steel core enhances rigidity and dimensional stability under pressure. This combination makes it ideal for static and dynamic sealing applications where chemical compatibility and robust performance are paramount.
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 and free of debris. 2. Carefully install the O-ring into the groove, avoiding stretching or twisting. 3. Verify proper seating of the O-ring before assembly of mating components.
