A proven choice for industrial professionals, this Buna-N O-ring features an inside diameter of 3.628 inches, an outside diameter of 6.914 inches, and a substantial cross-section of 0.269 inches. The Buna-N (Nitrile) compound offers excellent resistance to petroleum-based oils, greases, and hydraulic fluids, making it ideal for dynamic and static sealing applications. The integrated carbon steel provides enhanced structural integrity and rigidity, preventing extrusion under high pressure and ensuring longevity in demanding industrial settings across automotive, hydraulic, and general machinery sectors.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Thoroughly clean both the groove and the O-ring to remove any debris or contaminants. 2. Lightly lubricate the O-ring and the groove with a compatible lubricant to facilitate installation and prevent damage. 3. Carefully install the O-ring into its designated groove, ensuring it is seated evenly and without twisting.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incompatible lubricants that degrade the Buna-N material. | Always consult a chemical compatibility chart to select a lubricant that is safe for Buna-N and the specific operating environment. |
| Overstretching or twisting the O-ring during installation. | Gently roll or slide the O-ring into the groove, avoiding excessive stretching or twisting which can lead to premature failure. |
