Trusted by engineers across multiple sectors, this industrial O-ring is manufactured from high-quality Buna-N (Nitrile Butadiene Rubber) for superior resistance to oils, fuels, and hydraulic fluids. The precise dimensions of 5.453" Inside Diameter, 5.821" Outside Diameter, and a 0.159" Cross Section provide a tight, leak-proof seal when compressed within its mating groove. The carbon steel housing offers structural integrity and compatibility with a wide range of industrial fittings and machinery, making it ideal for static and dynamic sealing applications where chemical resistance and durability are paramount.
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 surfaces are clean and free of debris. 2. Carefully place the O-ring into its designated groove, avoiding stretching or twisting. 3. Apply a thin layer of compatible lubricant if necessary to facilitate seating and prevent damage during assembly.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-stretching the O-ring during installation. | Install the O-ring without excessive stretching. A slight twist may be necessary for larger diameters, but avoid prolonged elongation which can lead to premature failure. |
| Using incompatible lubricants or sealants. | Always consult the material compatibility chart for Buna-N and your specific application to select an appropriate lubricant or sealant that will not degrade the O-ring. |
| Installing on a dirty or damaged groove surface. | Thoroughly clean and inspect the groove for any nicks, burrs, or contaminants before O-ring installation. Damaged surfaces will compromise the seal. |
