Purpose-built for heavy-duty applications, this Buna-N O-ring features a precise Inside Diameter of 1.138 inches, an Outside Diameter of 3.990 inches, and a Cross Section of 0.216 inches. The Buna-N (Nitrile) material offers excellent resistance to oils, fuels, and many hydraulic fluids, making it ideal for applications involving petroleum-based substances. The carbon steel housing provides enhanced structural integrity and rigidity, crucial for maintaining seal integrity under significant mechanical stress and in corrosive environments. This combination ensures reliable static and dynamic sealing across a wide range 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 from debris. 2. Carefully position the O-ring within the groove, avoiding stretching or twisting. 3. Apply a light, compatible lubricant if recommended for the specific application to facilitate installation and prevent damage.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fasteners that compress the O-ring beyond its designed limit. | Adhere to specified torque values for all fasteners to prevent extrusion or permanent deformation of the O-ring. |
| Using incompatible lubricants or cleaning agents that degrade Buna-N material. | Consult the O-ring manufacturer's compatibility chart and use only recommended lubricants and cleaning agents. |
