A high-performance industrial component, this Buna-N O-ring features a precise inside diameter of 4.232 inches, an outside diameter of 7.779 inches, and a cross-section of 0.113 inches. The Buna-N (Nitrile Butadiene Rubber) material offers excellent resistance to oils, fuels, and many hydraulic fluids, making it suitable for a wide range of industrial environments. The carbon steel housing provides structural support and enhanced durability in high-pressure or abrasive conditions. This combination ensures reliable sealing performance and extended service life in dynamic and static sealing applications.
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 and free of debris. 2. Carefully position the O-ring within the groove, avoiding stretching or twisting. 3. Apply a light lubricant compatible with Buna-N if necessary to ease installation and prevent damage.
