Precision-manufactured to tight tolerances, this Buna-N O-ring features an Inside Diameter of 9.420 inches, an Outside Diameter of 0.404 inches, and a Cross Section of 0.256 inches. The Buna-N (Nitrile) material provides excellent resistance to oils, fuels, hydraulic fluids, and many common chemicals, while the carbon steel core offers structural integrity and resistance to deformation under pressure. This combination makes it ideal for static and dynamic sealing applications where resistance to petroleum-based substances is critical.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the groove is clean and free of debris. 2. Lightly lubricate the O-ring with a compatible lubricant. 3. Carefully install the O-ring into the groove, avoiding stretching or twisting.
