Precision-manufactured to tight tolerances, this industrial O-ring boasts an inside diameter of 7.556 inches, an outside diameter of 5.406 inches, and a cross-section of 0.122 inches. The Buna-N (Nitrile) elastomer offers excellent resistance to oils, fuels, and many hydraulic fluids, while the 304 stainless steel housing provides robust structural integrity and corrosion resistance. This combination ensures dependable sealing performance in a wide range of operating temperatures and pressures, making it suitable for demanding industrial environments where chemical compatibility and mechanical strength are critical.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating groove is clean, free of debris, and meets design specifications. 2. Carefully stretch the O-ring over the component, avoiding excessive force or sharp tools that could nick or cut the elastomer. 3. Seat the O-ring fully within its designated groove, confirming it is not twisted or pinched.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening the assembly, which can excessively compress and extrude the O-ring. | Follow torque specifications for the assembly and ensure the groove design provides adequate gland fill to prevent extrusion. |
| Using incompatible lubricants or cleaning agents that degrade the Buna-N material. | Consult a chemical compatibility chart for Buna-N and use only approved lubricants or cleaning agents. |
| Installing a twisted or pinched O-ring, leading to immediate seal failure. | Visually inspect the O-ring before and during installation to ensure it is seated flat and uniformly within the groove. |
