A high-performance industrial component, this Buna-N O-ring is engineered for demanding sealing applications. Featuring an inside diameter of 7.100 inches, an outside diameter of 3.150 inches, and a cross-section of 0.180 inches, it offers a precise fit for established groove dimensions. The Buna-N (Nitrile) material provides excellent resistance to oils, fuels, hydraulic fluids, and many solvents, making it suitable for a wide range of industrial machinery, hydraulic systems, and pneumatic equipment where moderate temperatures and exposure to non-aromatic hydrocarbons are common.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Clean and inspect the mating groove and sealing surfaces to ensure they are free of debris, burrs, and damage. 2. Lightly lubricate the O-ring and groove with a compatible lubricant to prevent tearing and facilitate insertion. 3. Carefully install the O-ring into the groove, ensuring it sits flush and is not twisted.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening or excessive compression during installation. | Ensure the O-ring is seated properly within its groove and avoid over-compressing, which can lead to premature wear and sealing failure. |
| Using incompatible lubricants or cleaning agents. | Always consult a chemical compatibility chart for Buna-N to select lubricants and cleaning agents that will not degrade the elastomer. |
