A high-performance industrial component, this Buna-N O-ring (Nylon material) features a nominal inside diameter of 4.981 inches, an outside diameter of 4.776 inches, and a cross-section of 0.104 inches. Buna-N (Nitrile Butadiene Rubber) offers excellent resistance to oils, fuels, hydraulic fluids, and many solvents, making it ideal for general-purpose industrial sealing. The inherent strength of the Nylon substrate enhances its durability and resistance to extrusion under pressure. It is designed for static and dynamic sealing applications where a reliable barrier against leakage is paramount, commonly found in hydraulic systems, pneumatic equipment, and automotive 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, dry, and free of debris. 2. Carefully lubricate the O-ring with a compatible lubricant to prevent damage during installation. 3. Gently install the O-ring into the groove, avoiding stretching or twisting, ensuring it sits flush.
