Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-stretching the O-ring during installation.Stretch only as much as necessary to fit into the groove. Excessive stretching can lead to premature failure and leaks.
Using a lubricant incompatible with silicone.Always use lubricants recommended for silicone O-rings to prevent material degradation.

Common Applications

  • Food and Beverage Processing Equipment
  • Medical Devices and Pharmaceutical Equipment
  • Automotive Seals and Gaskets

⚠️ Engineering Warnings

  • Not suitable for prolonged contact with high-concentration acids or bases.
