A high-performance industrial component, this Buna-N O-ring is precisely manufactured with an Inside Diameter (ID) of 8.090 inches, an Outside Diameter (OD) of 4.002 inches, and a cross-sectional diameter (CS) of 0.115 inches. Buna-N (Nitrile Butadiene Rubber) offers excellent resistance to petroleum-based oils, fuels, hydraulic fluids, and water, making it suitable for a wide range of industrial sealing applications. Its inherent resilience and compression set resistance ensure long-term sealing effectiveness under moderate pressure and temperature conditions.
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 lubricate the O-ring with a compatible lubricant to prevent tearing during installation. 3. Gently place the O-ring into the groove, ensuring it is seated evenly without twisting.
