Manufactured under strict quality controls, this 3.154" outside diameter, 0.115" inside diameter, and 0.257" cross-section O-ring utilizes a Buna-N (Nitrile) elastomer for excellent resistance to oils, fuels, and many hydraulic fluids. The integrated 316 stainless steel housing provides superior corrosion resistance, high tensile strength, and thermal stability, making it ideal for high-pressure and chemically aggressive environments. This design ensures reliable sealing across a wide temperature range, preventing leakage and contamination.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating surfaces are clean and free of debris. 2. Lubricate the O-ring and groove lightly with a compatible lubricant. 3. Carefully install the O-ring, avoiding stretching or twisting, into its designated groove.
