Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a lubricant incompatible with Silicone and the application's fluid environment.Consult compatibility charts or product datasheets to select a lubricant that will not degrade the O-ring or contaminate the system.
Excessive stretching or twisting of the O-ring during installation.Handle the O-ring with care, ensuring it is placed into the groove without undue force. Gentle manipulation is key to preventing damage.

Common Applications

  • High-pressure fluid power systems
  • Automotive sealing applications (e.g., engine components)
  • Aerospace fluid and fuel systems

⚠️ Engineering Warnings

  • Verify material compatibility with the specific operating environment, including media and temperature.
  • Do not exceed the maximum recommended operating pressure or temperature for the O-ring material.
