Trusted by engineers across multiple sectors, this Buna-N (Nitrile) O-ring boasts precise dimensions with an Inside Diameter of 7.820 inches, an Outside Diameter of 2.785 inches, and a standard 0.114-inch cross-section. Its robust nitrile butadiene rubber composition provides excellent resistance to petroleum-based oils, fuels, and hydraulic fluids, making it a preferred choice for static and dynamic sealing in moderate temperature environments. This material also exhibits good abrasion resistance and a wide operating temperature range.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the groove dimensions precisely match the O-ring's cross-section and diameter for optimal compression. 2. Lubricate the O-ring and the groove with a compatible lubricant, such as silicone grease or a petroleum jelly, to prevent damage during installation. 3. Carefully install the O-ring into the groove, avoiding any stretching or twisting, and ensure it sits flush without any protruding sections.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening the gland, leading to excessive compression and premature O-ring failure. | Adhere to manufacturer's recommended gland design and compression values, typically 10-25% of the cross-section. |
| Using incompatible lubricants that can degrade the Buna-N material. | Always use lubricants specifically approved for Buna-N (Nitrile) applications. |
| Stretching or twisting the O-ring during installation, causing nicks or tears. | Gently roll or push the O-ring into the groove, ensuring it's seated evenly and without distortion. |
