Precision-manufactured to tight tolerances, this Buna-N O-ring features an Inside Diameter of 5.920 inches, an Outside Diameter of 3.457 inches, and a Cross Section of 0.130 inches. The nitrile (Buna-N) material offers excellent resistance to oil, fuels, and many hydraulic fluids, making it ideal for dynamic and static seal applications. The integrated carbon steel provides structural support and enhanced crush resistance, particularly in high-pressure systems where standard elastomeric O-rings might fail. This combination ensures long-term performance and prevents leakage in demanding industrial settings.
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 is clean, dry, and free from burrs or contaminants. 2. Carefully place the O-ring into the groove, avoiding excessive stretching or twisting. 3. Verify proper seating and alignment before assembling mating components.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overstretching the O-ring during installation, leading to premature failure and leakage. | Install the O-ring without excessive tension, utilizing its elasticity to fit snugly within the groove. |
| Using the wrong O-ring material for the specific fluid or temperature, compromising seal integrity. | Confirm the Buna-N material is compatible with the operating environment and fluids to be sealed. |
