A proven choice for industrial professionals, this Buna-N O-ring is engineered for exceptional durability and sealing integrity. With an inside diameter of 1.288 inches, an outside diameter of 4.337 inches, and a precise cross-section of 0.215 inches, it conforms reliably to groove specifications. Buna-N (Nitrile Butadiene Rubber) exhibits excellent resistance to petroleum-based oils, fuels, and hydraulic fluids, making it ideal for a wide range of static and dynamic sealing applications in manufacturing, automotive, and fluid power systems. Its broad temperature range and cost-effectiveness further solidify its position as a go-to sealing solution.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Clean both the O-ring and the groove thoroughly. 2. Lightly lubricate the O-ring with a compatible lubricant. 3. Carefully place the O-ring into the groove, ensuring it is seated without twists or damage.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong lubricant, which can degrade Buna-N. | Always use lubricants specifically recommended for Buna-N rubber and the application's fluid. |
| Forcing the O-ring into the groove, causing cuts or nicks. | Ensure the groove is clean and the O-ring is properly sized. Use appropriate tools if necessary, but avoid sharp edges. |
