Manufactured under strict quality controls, this Buna-N O-ring features an inside diameter of 0.205 inches, an outside diameter of 3.475 inches, and a 0.100-inch cross-section. The Buna-N (Nitrile) elastomer provides excellent resistance to oils, fuels, and many hydraulic fluids. The 316 stainless steel construction offers superior corrosion resistance, making it suitable for harsh chemical or marine environments. This combination ensures a robust and long-lasting seal in a wide array of industrial machinery and equipment.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the sealing groove is clean and free of debris. 2. Carefully stretch the O-ring over the smaller component or into the groove, avoiding excessive force or sharp tools. 3. Gently seat the O-ring within the groove, ensuring no twisting or pinching occurs before assembly of mating parts.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fasteners, which can over-compress and damage the O-ring. | Tighten fasteners to the manufacturer's specified torque values to prevent over-compression. |
| Using sharp or abrasive tools during installation, which can nick or cut the O-ring. | Utilize only non-metallic, rounded installation tools or adequate lubrication for smooth O-ring placement. |
| Selecting an O-ring material incompatible with the fluid or operating temperature. | Verify the Buna-N material's compatibility with the specific application's chemical exposure and temperature range before installation. |
