Purpose-built for heavy-duty applications, this industrial O-ring features a precise Inside Diameter of 2.147 inches, an Outside Diameter of 5.867 inches, and a 0.196-inch cross-section. Fabricated from Buna-N (Nitrile Butadiene Rubber), it offers excellent resistance to oils, fuels, hydraulic fluids, and a wide range of solvents. This material's inherent resilience and good compression set properties make it ideal for static and dynamic sealing applications in demanding industrial machinery, hydraulic systems, pneumatic equipment, and automotive components where reliable fluid containment is critical.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure both sealing surfaces are clean, free from debris, and smooth. 2. Lightly lubricate the O-ring and the sealing groove with a compatible lubricant. 3. Carefully install the O-ring into the groove, ensuring it is not twisted or pinched.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a lubricant incompatible with Buna-N. | Consult a chemical compatibility chart to select a lubricant recommended for Buna-N, such as silicone or petroleum-based greases. |
| Overstretching or twisting the O-ring during installation. | Gently roll or slide the O-ring into the groove, avoiding excessive force or deformation to prevent premature failure. |
