Specified by design engineers worldwide, this Buna-N industrial O-ring features precise dimensions of 4.781 inches Inside Diameter (ID), 8.236 inches Outside Diameter (OD), and a 0.231-inch Cross Section (CS). The Buna-N (Nitrile) compound offers excellent resistance to petroleum-based oils, hydraulic fluids, and many other chemicals, making it suitable for moderate temperature applications. The integrated carbon steel housing enhances structural integrity and provides superior resistance to extrusion and mechanical damage in high-pressure and high-stress environments, ensuring long-term operational reliability.
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 stretching or nicking with sharp tools. 3. Position the O-ring squarely within the groove, ensuring no twists or distortions before assembly of mating components.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force during installation, leading to O-ring damage. | Apply gentle, even pressure during installation. Use appropriate, non-metallic tools if necessary to guide the O-ring into place. |
| Incorrect lubricant selection, causing O-ring swelling or degradation. | Always consult chemical compatibility charts to select a lubricant that is compatible with Buna-N and the operating environment. |
| Installing a twisted or distorted O-ring. | Visually inspect the O-ring before and during installation to ensure it sits flat and evenly within the groove, without any twists. |
