Precision-manufactured to tight tolerances, this Buna-N (Nitrile Butadiene Rubber) O-ring boasts an Inside Diameter (ID) of 3.175 inches, an Outside Diameter (OD) of 6.986 inches, and a Cross Section (CS) of 0.080 inches. Buna-N provides excellent resistance to oils, fuels, hydraulic fluids, and many common solvents, making it ideal for a wide range of static and dynamic sealing applications. Its operating temperature range typically spans from -40°F to +257°F (-40°C to +125°C), offering consistent performance in moderate to high-pressure systems. This material is a cost-effective choice for general-purpose sealing where chemical and thermal resistance are paramount.
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, dry, and free of burrs or debris. 2. Lubricate the O-ring and mating groove lightly with a compatible lubricant (e.g., silicone grease). 3. Carefully install the O-ring into the groove, avoiding stretching or twisting.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong lubricant, which can degrade the Buna-N material. | Always consult compatibility charts or use a lubricant specifically recommended for Buna-N seals. |
| Overtightening fasteners, which can over-compress and damage the O-ring. | Adhere to specified torque values for the assembly to prevent premature seal failure. |
