A proven choice for industrial professionals, this Buna-N O-ring (Nitrile) boasts a precise 3.270" inside diameter, 2.149" outside diameter, and a 0.252" cross-section. Buna-N, also known as Nitrile Butadiene Rubber, offers exceptional resistance to petroleum-based oils, fuels, and hydraulic fluids, along with good abrasion and tear strength. This material is well-suited for moderate temperature ranges and is a cost-effective solution for general-purpose sealing in hydraulic systems, pneumatic equipment, and automotive applications where oil and fuel exposure is common.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the groove and mating surfaces are clean and free of debris. 2. Carefully stretch the O-ring over the component, avoiding excessive force or sharp tools. 3. Position the O-ring squarely within its groove to prevent twisting.
