Designed for demanding industrial environments, this Buna-N O-ring features an inside diameter of 3.424 inches, an outside diameter of 7.925 inches, and a cross-section of 0.083 inches. Buna-N (Nitrile Butadiene Rubber) offers excellent resistance to petroleum-based oils, hydraulic fluids, and a broad range of chemicals, making it ideal for applications exposed to these substances. Its resilience and elasticity contribute to long-lasting, leak-free performance in pumps, valves, and hydraulic systems.
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 surfaces are clean and free from debris. 2. Carefully stretch the O-ring over the smaller diameter of the assembly or into the groove. 3. Gently roll or seat the O-ring into its designated groove, avoiding excessive stretching or twisting.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overstretching the O-ring during installation, leading to premature failure. | Use appropriate installation tools and techniques to minimize stress on the O-ring. Install in sections if necessary and roll into the groove. |
| Installing on a damaged or dirty groove surface, compromising the seal. | Thoroughly inspect and clean all groove surfaces before installation. Address any nicks, burrs, or corrosion. |
