Trusted by engineers across multiple sectors, this industrial O-ring features a precise 6.493" inside diameter, 4.378" outside diameter, and a 0.268" cross-section. The Buna-N elastomer offers excellent resistance to oils, fuels, and many hydraulic fluids, while the 316 stainless steel housing provides exceptional corrosion resistance, making it suitable for use in aggressive chemical environments and high-temperature applications. This combination ensures a leak-proof seal under significant pressure and thermal fluctuations.
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 from burrs or debris. 2. Carefully position the O-ring within its designated groove, avoiding stretching or twisting. 3. Apply a thin, compatible lubricant to the O-ring and groove if recommended for the specific application to facilitate seating and prevent damage during assembly.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fasteners, causing O-ring extrusion or compression set. | Adhere to specified torque values for all fasteners to ensure proper sealing pressure without overstressing the O-ring. |
| Using incompatible lubricants or cleaning agents that degrade the Buna-N elastomer. | Consult material compatibility charts and use only lubricants and cleaning agents explicitly recommended for Buna-N and the specific operating environment. |
