Purpose-built for heavy-duty applications, this Buna-N O-ring boasts an inside diameter of 1.395", an outside diameter of 7.875", and a cross-section of 0.185". The Buna-N (Nitrile Butadiene Rubber) material provides excellent resistance to oils, fuels, hydraulic fluids, and certain solvents, making it ideal for systems operating within a temperature range of -40°F to +257°F (-40°C to +125°C). The brass composition enhances its durability and compatibility in specific corrosive environments where standard metal components might degrade. This o-ring is engineered for static and dynamic sealing in hydraulic and pneumatic systems, pumps, valves, and engine components.
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. Lightly lubricate the O-ring with a compatible lubricant, such as silicone grease or petroleum jelly. 3. Carefully install the O-ring into the designated groove, avoiding any twisting or stretching beyond its natural state.
