Specified by design engineers worldwide, this industrial O-ring boasts an Inside Diameter of 8.246 inches and an Outside Diameter of 6.248 inches, with a precise Cross Section of 0.088 inches. The Buna-N elastomer offers excellent resistance to petroleum-based oils, greases, and hydraulic fluids, while the 316 stainless steel construction ensures superior corrosion resistance, particularly in marine and chemical processing environments. This combination makes it ideal for static and dynamic sealing in pumps, valves, and machinery subjected to harsh operating conditions and aggressive media.
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 burrs or debris. 2. Lightly lubricate the O-ring with a compatible lubricant to prevent tearing during installation. 3. Carefully install the O-ring into its designated groove, ensuring it is seated evenly and not twisted.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening during assembly, which can crush the O-ring and compromise its sealing integrity. | Follow specified torque values for fasteners and ensure proper gland design to avoid over-compression. |
| Using incompatible lubricants or cleaning agents that can degrade the Buna-N material. | Consult material compatibility charts for recommended lubricants and cleaning solutions. |
