Built to exacting engineering tolerances, this Buna-N (Nitrile Butadiene Rubber) o-ring features an Inside Diameter of 9.191 inches, an Outside Diameter of 9.942 inches, and a precise Cross Section of 0.181 inches. Buna-N offers excellent resistance to petroleum-based oils, greases, hydraulic fluids, and water, making it ideal for general-purpose sealing in industrial machinery, automotive systems, and fluid power applications. Its operating temperature range is typically -30°F to 250°F (-34°C to 121°C), ensuring durability in moderate temperature conditions. The inherent resilience of Buna-N allows for effective compression sealing.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating groove is clean, free of debris, and properly dimensioned for the o-ring's cross-section. 2. Lightly lubricate the o-ring and the groove with a compatible lubricant (e.g., silicone grease or a drop of the fluid being sealed) to prevent tearing during installation. 3. Carefully install the o-ring into the groove, avoiding stretching or twisting, and ensure it is seated uniformly.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening or excessive stretching during installation | Install the o-ring without undue force or stretching, ensuring it sits flush within the groove. |
| Using incompatible lubricants or cleaning agents | Consult compatibility charts to ensure lubricants and cleaning agents do not degrade the Buna-N material. |
| Installing into a damaged or dirty groove | Thoroughly inspect and clean the groove before installation to prevent premature seal failure. |
