Built to exacting engineering tolerances, this O-ring boasts an Inside Diameter of 2.956 inches, an Outside Diameter of 10.375 inches, and a Cross Section of 0.154 inches. The Buna-N (Nitrile Butadiene Rubber) compound provides excellent resistance to oils, fuels, and many hydraulic fluids, operating effectively across a temperature range of -40°F to 257°F (-40°C to 125°C). The 304 stainless steel housing offers exceptional corrosion resistance and mechanical strength, making this seal ideal for high-pressure, corrosive, and abrasive industrial environments. Its rigid construction also prevents extrusion under pressure, enhancing sealing integrity and extending service life in demanding applications.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Thoroughly clean mating groove and O-ring surfaces to remove debris and contaminants. 2. Apply a thin, uniform layer of compatible lubricant to the O-ring and groove. 3. Carefully install the O-ring into the groove, ensuring it is seated without twisting or stretching. 4. Verify proper O-ring placement and integrity before assembly completion.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong lubricant | Always use a lubricant compatible with both the Buna-N material and the system media to prevent swelling or degradation of the seal. |
| Overtightening fasteners | Overtightening can cause excessive compression, leading to O-ring extrusion or premature failure. Follow torque specifications precisely. |
| Installing a twisted O-ring | A twisted O-ring will create leakage paths and significantly reduce its lifespan. Ensure the O-ring sits flat and uniformly in the groove. |
