Built to exacting engineering tolerances, this industrial O-ring features a precise inside diameter of 4.728 inches, an outside diameter of 7.138 inches, and a cross-section of 0.172 inches. The Buna-N (Nitrile Butadiene Rubber) compound provides excellent resistance to oils, fuels, and many hydraulic fluids, while the 304 stainless steel housing offers exceptional corrosion resistance and structural integrity. This combination ensures reliable and long-lasting sealing in high-pressure and aggressive chemical environments, making it ideal for static and dynamic sealing applications within pumps, valves, and machinery.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating surfaces are clean, dry, and free of debris. 2. Carefully position the O-ring within its designated groove, avoiding any stretching or twisting. 3. Apply a thin, compatible lubricant to the O-ring and mating surface if recommended for the application to facilitate assembly and prevent damage.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overstretching the O-ring during installation. | Gently guide the O-ring into the groove without excessive pulling. If necessary, use specialized O-ring installation tools. |
| Using incompatible lubricants or sealants. | Always consult the material compatibility chart for Buna-N and the specific fluids in the application. Use only approved lubricants. |
| Installing on dirty or damaged mating surfaces. | Thoroughly clean and inspect mating surfaces for any nicks, burrs, or corrosion before installation to prevent leaks and premature failure. |
