Designed for demanding industrial environments, this Buna-N O-ring features a precise inside diameter of 7.831 inches, an outside diameter of 0.326 inches, and a substantial cross-section of 0.117 inches. The Buna-N (Nitrile) material provides excellent resistance to oils, fuels, hydraulic fluids, and many other chemicals, making it suitable for a wide range of static and dynamic sealing applications. The brass construction offers added structural integrity and corrosion resistance in specific environments. This O-ring is engineered for optimal performance in moderate temperature ranges and where chemical compatibility is paramount.
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 surfaces are clean, dry, and free from debris or damage. 2. Carefully place the O-ring into the groove, avoiding any stretching or twisting. 3. Verify the O-ring is seated evenly and without pinch points before assembly. 4. If used in a dynamic application, lubricate lightly with a compatible lubricant as per system specifications.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overstretching the O-ring during installation. | Handle the O-ring gently and avoid excessive stretching, which can lead to premature failure and leakage. |
| Using incompatible lubricants or cleaning agents. | Always refer to chemical compatibility charts for both the O-ring material and any lubricants or cleaning agents used in conjunction with it. |
| Installing with a damaged or unclean groove. | Thoroughly inspect and clean the groove before installation to prevent leaks and damage to the O-ring. |
