Engineered for reliability and performance, this Buna-N O-ring is constructed from a robust brass material, offering excellent chemical resistance and durability. With an inside diameter of 7.211 inches, an outside diameter of 8.192 inches, and a precise cross-section of 0.120 inches, it is designed for optimal compression and sealing in static and dynamic applications. The Buna-N compound provides good resistance to petroleum-based oils, fuels, and hydraulic fluids, making it suitable for a wide range of industrial machinery, automotive systems, and hydraulic power units where reliable, leak-free operation is paramount.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating grooves are clean, dry, and free of any debris or sharp edges. 2. Carefully lubricate the O-ring and the groove with a compatible lubricant (e.g., silicone grease or a petroleum-based lubricant, depending on the application). 3. Gently install the O-ring into the groove, ensuring it sits evenly and without twisting.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fasteners, which can compress the O-ring beyond its elastic limit and cause premature failure. | Use torque wrenches to adhere to specified fastener torque values and avoid excessive compression. |
| Using incompatible lubricants that can degrade the Buna-N material or the fluid being sealed. | Always verify lubricant compatibility with Buna-N and the specific fluid medium before application. |
| Installing the O-ring with a twist, which can create leak paths and reduce its sealing effectiveness. | Ensure the O-ring is installed straight and without rotation in the groove. |
