Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, which can damage the O-ring.Apply gentle, even pressure and ensure the O-ring is seated correctly in the groove without distortion.
Installing the wrong size O-ring for the application's groove dimensions.Always verify the O-ring's dimensions (ID, OD, CS) against the groove specifications before installation.

Common Applications

  • High-temperature sealing in ovens and kilns
  • Low-temperature fluid sealing in refrigeration systems
  • Medical equipment and pharmaceutical processing seals

⚠️ Engineering Warnings

  • Ensure compatibility of the silicone material with all media it will contact, as certain aggressive chemicals can degrade silicone.
  • Avoid exposure to steam or hot water beyond the material's rated temperature to prevent premature failure.
