A high-performance industrial component, this O-ring features an inside diameter of 3.018 inches, an outside diameter of 8.822 inches, and a cross-section of 0.158 inches. The 316 stainless steel construction provides superior corrosion resistance, particularly in harsh chemical and saltwater environments. The Buna-N (Nitrile Butadiene Rubber) offers excellent resistance to oils, fuels, and many common industrial fluids, making it suitable for a wide range of dynamic and static sealing applications where temperature ranges from -40°F to +250°F are encountered. Its robust design ensures a tight seal against leakage under significant pressure.
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, free of debris, and properly dimensioned for the O-ring. 2. Lightly lubricate the O-ring with a compatible lubricant to facilitate installation and prevent damage. 3. Carefully install the O-ring into the groove, avoiding any stretching or twisting.
