Purpose-built for heavy-duty applications, this Buna-N O-ring boasts a precise inside diameter of 1.872 inches, an outside diameter of 4.493 inches, and a substantial cross-section of 0.207 inches. The Buna-N (Nitrile Butadiene Rubber) material offers excellent resistance to oils, fuels, hydraulic fluids, and general chemicals, making it suitable for a wide array of industrial fluid power and general mechanical systems. The brass component ensures compatibility with specific fluid or environmental requirements where non-ferrous metals are mandated, providing superior durability and chemical stability in its intended operational envelope.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating surfaces are clean, dry, and free of debris. 2. Carefully compress and install the O-ring into its designated groove, avoiding excessive stretching or twisting. 3. Verify proper seating and seal integrity before applying operational pressure.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening during installation, leading to compression set and premature failure. | Install with minimal compression necessary to achieve a seal, ensuring the O-ring is not deformed beyond its elastic limits. |
| Using the wrong O-ring material for the specific fluid or operating temperature. | Always verify Buna-N compatibility with the chemical and temperature conditions of the application to prevent degradation and leakage. |
