Built to exacting engineering tolerances, this Buna-N O-ring features a 0.784-inch inside diameter, a 3.269-inch outside diameter, and a 0.154-inch cross-section. The Buna-N (Nitrile) elastomer offers excellent resistance to petroleum-based oils, greases, hydraulic fluids, and water, making it suitable for a wide range of industrial sealing tasks. The carbon steel housing enhances structural integrity and durability in high-pressure or abrasive conditions. Its Shore A hardness of 70 ± 5 ensures optimal compression set resistance and sealing efficiency across its operating temperature range of -40°F to +225°F (-40°C to +107°C).
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 debris or damage. 2. Carefully position the O-ring within the groove, avoiding excessive stretching or twisting. 3. Apply a thin layer of compatible lubricant if recommended for the specific application and elastomer to facilitate assembly and prevent damage.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force during installation, leading to O-ring nicks or tears. | Employ gentle, controlled pressure during installation. Utilize appropriate tools if necessary for proper seating. |
| Installing an O-ring into a contaminated groove. | Thoroughly clean both the O-ring and the mating groove surfaces before installation to prevent premature seal failure. |
