Trusted by engineers across multiple sectors, this Buna-N O-ring boasts a nominal inside diameter of 4.140 inches and an outside diameter of 2.142 inches, with a precise 0.083-inch cross-section. The Buna-N (Nitrile) compound offers excellent resistance to oils, fuels, and many hydraulic fluids, making it ideal for general-purpose sealing applications. Its inherent toughness and resilience contribute to a dependable seal under moderate pressure and temperature fluctuations. The brass element, while not the primary sealing material, may indicate a specific housing or component compatibility for brass systems, requiring consideration for galvanic corrosion if in direct, prolonged contact with dissimilar metals in aggressive environments.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the sealing groove and mating surfaces are clean, free of debris, and undamaged. 2. Lightly lubricate the O-ring with a compatible lubricant (e.g., silicone or petroleum jelly, depending on service fluid) to facilitate installation and prevent damage. 3. Carefully install the O-ring into its designated groove, ensuring it is not twisted or stretched beyond its elastic limit. Avoid using sharp tools.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect lubrication that is incompatible with the service fluid or O-ring material. | Consult compatibility charts to select a lubricant that is chemically inert to both the Buna-N material and the fluid it will be sealing against. |
| Over-stretching or twisting the O-ring during installation, leading to premature failure. | Install the O-ring gently, allowing it to seat naturally in the groove. Use a lubricant to ease insertion and prevent twisting. |
