Precision-manufactured to tight tolerances, this Buna-N O-ring features an inside diameter of 3.909 inches, an outside diameter of 9.057 inches, and a cross-section of 0.146 inches. Buna-N (Nitrile) rubber is selected for its excellent resistance to petroleum-based oils, fuels, and hydraulic fluids, as well as good abrasion and tear resistance. This makes it a cost-effective and reliable choice for general-purpose sealing in static and dynamic applications where exposure to these media is common. Operating temperature range is typically -40°F to +257°F (-40°C to +125°C).
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating groove surfaces are clean and free of debris. 2. Lubricate the O-ring and groove with a compatible lubricant if necessary. 3. Carefully install the O-ring into the groove, avoiding any twisting or stretching.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an O-ring with incorrect dimensions for the groove. | Always verify the O-ring's inside diameter, outside diameter, and cross-section against the groove's design specifications. |
| Over-stretching or twisting the O-ring during installation. | Gently roll or push the O-ring into the groove, ensuring it seats evenly without distortion. |
| Installing in an incompatible chemical environment. | Confirm that the Buna-N material is resistant to the specific fluids or gases it will be exposed to. |
