Built to exacting engineering tolerances, this Buna-N O-ring features an inside diameter of 8.698 inches, an outside diameter of 1.642 inches, and a 0.187-inch cross-section. Buna-N, also known as Nitrile butadiene rubber, offers excellent resistance to petroleum-based oils, fuels, and hydraulic fluids, making it ideal for applications involving such media. Its inherent resilience and good mechanical properties ensure a reliable seal under moderate temperatures and pressures, preventing leaks and contamination. The precise geometric specifications are crucial for achieving optimal compression and groove conformance in static and dynamic sealing scenarios.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating surfaces are clean, free of debris, and properly lubricated with compatible lubricant. 2. Carefully position the O-ring into its designated groove, avoiding any stretching or twisting. 3. Assemble mating components, applying even pressure to compress the O-ring and establish a seal.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fasteners, leading to excessive compression and premature O-ring failure. | Adhere to specified torque values for all fasteners to ensure controlled compression of the O-ring. |
| Using incompatible lubricants that degrade the Buna-N material. | Consult material compatibility charts to select a lubricant suitable for Buna-N and the operating environment. |
