Built to exacting engineering tolerances, this Buna-N O-ring features an inside diameter of 4.474 inches, an outside diameter of 5.190 inches, and a cross-section of 0.220 inches. Buna-N (Nitrile Butadiene Rubber) offers excellent resistance to oils, fuels, hydraulic fluids, and many industrial chemicals, making it suitable for moderate temperature applications (typically -40°F to 212°F). Its robust material properties and precise dimensional accuracy guarantee a secure, leak-proof seal in dynamic and static applications, preventing fluid loss and contamination.
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 is clean, free of debris, and properly lubricated with a compatible lubricant. 2. Carefully stretch the O-ring over the smaller diameter of the assembly or into the groove, avoiding overstretching. 3. Press the O-ring firmly into the groove, ensuring it is seated evenly and without twists.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening during installation, leading to permanent deformation. | Install with sufficient tension to create a seal but avoid excessive force that could damage the O-ring. |
| Using incompatible lubricants or cleaning agents. | Always verify lubricant and cleaning agent compatibility with Buna-N material to prevent degradation. |
| Allowing the O-ring to twist in the groove. | Ensure the O-ring is seated flat and evenly in the groove during installation; a twisted O-ring will compromise the seal. |
