Specified by design engineers worldwide, this industrial O-ring features a precise inside diameter of 8.225 inches, an outside diameter of 8.335 inches, and a cross-section of 0.108 inches. The Buna-N (Nitrile Butadiene Rubber) material offers excellent resistance to oils, fuels, hydraulic fluids, and a wide range of chemicals, making it suitable for high-pressure systems. The brass housing provides structural integrity and corrosion resistance in aggressive environments. Operating temperature range typically spans from -40°F to +212°F (-40°C to +100°C).
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure both sealing surfaces are clean, dry, and free from debris. 2. Carefully place the O-ring into its designated groove, ensuring it is seated evenly without any twists or kinks. 3. Assemble the components, applying light and consistent pressure to achieve a proper seal.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fittings | Tighten fittings to the manufacturer's recommended torque specification to avoid over-compression and damage to the O-ring. |
| Using incorrect lubricant | Apply only approved lubricants compatible with Buna-N and the service fluid to prevent premature degradation of the O-ring. |
| Installing a twisted O-ring | Inspect the O-ring for twists before installation and ensure it is laid flat and evenly within the groove. |
