Built to exacting engineering tolerances, this O-ring boasts an inside diameter of 3.788 inches, an outside diameter of 7.411 inches, and a cross-section of 0.249 inches. The Buna-N (Nitrile Butadiene Rubber) compound provides excellent resistance to petroleum-based oils, fuels, and many hydraulic fluids. The 304 stainless steel housing offers exceptional corrosion resistance, high tensile strength, and durability in aggressive chemical environments and extreme temperatures. This combination makes it ideal for static and dynamic sealing applications in pumps, valves, actuators, and fluid power systems where reliability and longevity are paramount.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Clean mating surfaces thoroughly to remove any debris or contaminants. 2. Carefully inspect the O-ring for damage or defects prior to installation. 3. Install the O-ring into its designated groove, ensuring it is properly seated and not twisted.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Installing a twisted O-ring. | Ensure the O-ring is laid straight into its groove without any twists, as this can lead to immediate leakage and premature failure. |
| Using excessive force during installation. | Apply gentle, even pressure. If significant force is required, re-check groove dimensions and O-ring size for compatibility. |
