Engineered for reliability and performance, this Buna-N O-ring features a 4.388" inside diameter, an 8.289" outside diameter, and a 0.092" cross-section. The Buna-N (Nitrile) material provides excellent resistance to oils, fuels, and hydraulic fluids, making it suitable for a broad range of industrial environments. While the brass element is not a sealing material itself, it indicates the O-ring may be part of a specific assembly or component requiring brass compatibility. Optimal for static and low-dynamic seal applications where chemical resistance and cost-effectiveness are paramount.
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, free of debris, and undamaged. 2. Lubricate the O-ring and groove with a compatible lubricant to prevent tearing and facilitate installation. 3. Carefully place the O-ring into the groove, avoiding stretching or twisting, and ensure it is seated evenly.
