Specified by design engineers worldwide, this high-performance industrial O-ring offers a nominal Inside Diameter of 0.686 inches and an Outside Diameter of 4.077 inches, with a Cross Section of 0.196 inches. The Buna-N elastomer provides excellent resistance to oils, fuels, and hydraulic fluids, while the 316 stainless steel housing ensures superior corrosion resistance in aggressive chemical and marine applications. This combination makes it suitable for high-pressure systems, dynamic seals, and environments requiring extended service life and dependable sealing integrity.
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 or compress the O-ring to fit within the groove, avoiding any sharp tools that could nick or cut the sealing element. 3. Verify the O-ring is seated evenly and squarely within the groove before assembling the mating components.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incompatible lubricants that degrade Buna-N elastomer. | Always consult chemical compatibility charts for approved lubricants with Buna-N and 316 stainless steel. |
| Over-stretching or twisting the O-ring during installation, leading to premature failure. | Handle the O-ring gently, using appropriate tools if necessary, and ensure it lies flat within the groove without deformation. |
