Built to exacting engineering tolerances, this Buna-N O-ring offers a precise seal with an Inside Diameter of 2.559", an Outside Diameter of 0.906", and a Cross Section of 0.186". The nitrile butadiene rubber (Buna-N) provides excellent resistance to oils, fuels, and general chemicals, while the 316 stainless steel housing ensures superior strength, corrosion resistance in aggressive media, and thermal stability, making it ideal for high-pressure, high-temperature, and chemically challenging environments.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Clean sealing surfaces thoroughly to remove debris and contaminants. 2. Lightly lubricate the O-ring and groove with a compatible lubricant. 3. Carefully install the O-ring into the designated groove, ensuring it is not twisted or stretched.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incompatible lubricants that degrade the Buna-N material. | Always consult the chemical compatibility chart for Buna-N and select a lubricant specifically approved for the application. |
| Forcing the O-ring into the groove, causing nicks or tears. | Ensure the O-ring is properly sized for the groove and use a non-metallic tool if necessary for gentle insertion. |
