Specified by design engineers worldwide, this Buna-N O-ring features a 4.915-inch inside diameter, 8.893-inch outside diameter, and a 0.226-inch cross-section. The carbon steel core offers exceptional structural integrity and resistance to extrusion under high pressure, while the Buna-N (Nitrile) elastomer provides excellent resistance to oils, fuels, and hydraulic fluids. This combination ensures reliable sealing across a wide temperature range, making it suitable for static and dynamic applications in manufacturing, automotive, 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 mating groove is clean, free from debris, and properly lubricated with a compatible lubricant. 2. Carefully stretch the O-ring over the shaft or into the groove, avoiding any sharp tools that could nick or cut the seal. 3. Verify the O-ring is seated evenly and without twists or damage before assembling mating components.
