Manufactured under strict quality controls, this Buna-N O-ring features an inside diameter of 4.237", an outside diameter of 2.068", and a cross-section of 0.095". Buna-N (Nitrile) offers excellent resistance to oils, fuels, and many hydraulic fluids, making it ideal for applications involving petroleum-based products. The brass component provides corrosion resistance and material compatibility in specific environments. This combination ensures reliable sealing and longevity in moderate temperature and pressure ranges.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Clean both mating surfaces and the O-ring thoroughly. 2. Apply a thin layer of compatible lubricant to the O-ring and the groove. 3. Carefully install the O-ring into the designated groove, ensuring it is seated without twisting or pinching.
