Precision-manufactured to tight tolerances, this Buna-N O-ring features an Inside Diameter of 9.169 inches, an Outside Diameter of 3.064 inches, and a Cross Section of 0.206 inches. The 304 stainless steel housing ensures superior corrosion resistance and mechanical strength, making it ideal for high-pressure and chemically aggressive environments. Buna-N's excellent resilience and resistance to petroleum-based fluids, oils, and greases further enhance its suitability for static and dynamic sealing applications in hydraulic systems, pneumatic machinery, and general industrial equipment.
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, free of debris, and properly dimensioned. 2. Carefully stretch or compress the O-ring to fit within the groove, avoiding sharp tools or excessive force that could nick or damage the sealing surface. 3. Verify the O-ring is seated evenly and fully within the groove before assembling mating components.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force during installation, leading to cuts or abrasions on the O-ring surface. | Apply gentle, even pressure. Use appropriate lubricant if necessary to aid installation and prevent damage. |
| Installing the O-ring into a contaminated or improperly sized groove. | Thoroughly clean the groove before installation. Confirm groove dimensions meet O-ring specifications to ensure proper compression and sealing. |
