A proven choice for industrial professionals, this Buna-N O-ring boasts an inside diameter of 9.904 inches, an outside diameter of 8.986 inches, and a cross-section of 0.142 inches. The Buna-N (Nitrile) material provides excellent resistance to oils, fuels, hydraulic fluids, and many other chemicals, making it suitable for moderate temperature ranges and general-purpose sealing. The brass element in its construction signifies a specific application requirement or compatibility, often related to the mating components or fluid media. This O-ring is designed to maintain seal integrity under pressure, preventing leaks in critical systems.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating grooves are clean, free of debris, and properly dimensioned. 2. Lightly lubricate the O-ring with a compatible lubricant (e.g., silicone grease or a fluid from the intended application) for easier installation and to prevent damage. 3. Carefully install the O-ring into the groove, avoiding stretching or twisting, and ensuring it sits evenly.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overstretching the O-ring during installation. | Use appropriate lubrication and ensure the groove dimensions are correct to minimize the need for excessive stretching. |
| Using incompatible lubricants or cleaning agents. | Always verify lubricant and cleaning agent compatibility with Buna-N material and the specific application fluid. |
| Installing the O-ring into a damaged or dirty groove. | Thoroughly inspect and clean mating grooves before installation to prevent premature seal failure. |
