A high-performance industrial component, this Buna-N O-ring is engineered for critical sealing applications. It features a precise inside diameter of 7.032 inches and an outside diameter of 7.174 inches, with a cross-sectional diameter of 0.173 inches. The Buna-N (Nitrile Butadiene Rubber) material provides excellent resistance to oils, fuels, and many industrial chemicals, making it suitable for high-pressure systems. The integrated brass component offers dimensional stability and improved handling during installation. Its temperature range typically spans -40°F to +257°F (-40°C to +125°C), depending on the specific compound formulation.
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 shaft or into the groove, avoiding excessive force or sharp tools that could nick or cut the material. 3. Seat the O-ring fully into the groove, ensuring it is not twisted or kinked, which can compromise the seal's integrity.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force during installation, leading to nicks or tears in the O-ring. | Apply a thin layer of compatible lubricant to the O-ring and groove, and gently stretch or roll the O-ring into place, using hand pressure only. |
| Installing a twisted or kinked O-ring, which prevents proper sealing. | Visually inspect the O-ring before installation to ensure it is flat and undistorted, and confirm it is properly seated in the groove without any twists. |
