Manufactured under strict quality controls, this Buna-N (Nitrile Butadiene Rubber) industrial O-ring boasts a 5.547" inside diameter, a 10.729" outside diameter, and a 0.142" cross-section. Buna-N offers excellent resistance to petroleum-based oils, hydraulic fluids, water, and certain solvents, making it ideal for general-purpose sealing where moderate temperature and chemical exposure are expected. The brass material composition of the associated fitting complements the O-ring's sealing capabilities in a variety of industrial fluid power and mechanical systems.
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 smooth. 2. Lightly lubricate the O-ring and groove with a compatible lubricant. 3. Carefully install the O-ring into the groove, avoiding stretching or twisting, until it is fully seated.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong lubricant. | Always consult compatibility charts to ensure the lubricant is suitable for Buna-N and the application's fluids. |
| Over-stretching the O-ring during installation. | Gently roll or press the O-ring into the groove to prevent damage and ensure a proper seal. |
| Installing on a damaged or dirty groove. | Thoroughly inspect and clean the groove before installation to prevent leaks and premature failure. |
