Specified by design engineers worldwide, this industrial O-ring features an inside diameter of 7.667 inches, an outside diameter of 1.819 inches, and a critical cross-section of 0.248 inches. The Buna-N elastomer offers excellent resistance to oils, fuels, and hydraulic fluids, while the 304 stainless steel housing ensures exceptional durability and corrosion resistance in harsh chemical and high-pressure applications. This combination makes it ideal for static and dynamic sealing in petrochemical, automotive, and manufacturing machinery.
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 properly lubricated with a compatible lubricant. 2. Carefully position the O-ring within the groove, avoiding any stretching or twisting. 3. Apply even, controlled pressure to install the mating component, allowing the O-ring to seat properly.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening the mating component, which can lead to O-ring extrusion or damage. | Adhere to specified torque values for the assembly to prevent over-compression of the O-ring. |
| Using incompatible lubricants or cleaning agents that degrade the Buna-N material. | Consult material compatibility charts and use only approved lubricants and cleaning solutions for Buna-N. |
