Precision-manufactured to tight tolerances, this O-ring boasts an inside diameter of 3.732", an outside diameter of 4.055", and a cross-section of 0.180". The Buna-N compound offers excellent resistance to oils, fuels, and many hydraulic fluids, making it suitable for a broad spectrum of dynamic and static sealing applications. The 316 stainless steel construction provides superior corrosion resistance, particularly in marine, chemical processing, and food/beverage industries, and maintains its structural integrity across a wide temperature range (-40°F to +212°F).
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the groove or mating surfaces are clean, dry, and free from debris or damage. 2. Carefully position the O-ring into the designated groove, avoiding stretching or twisting. 3. Gently compress the O-ring during assembly to achieve a uniform fit.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening during installation, causing excessive compression and premature failure. | Apply only the necessary compression to achieve a seal; consult assembly drawings for recommended groove fill. |
| Using the wrong O-ring material for the fluid or environmental conditions. | Verify chemical compatibility and temperature range against the Buna-N and 316 stainless steel specifications. |
