Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, which can lead to O-ring damage.Gently seat the O-ring into the groove, using a non-metallic tool if needed, ensuring it remains untwisted.
Installing the O-ring on contaminated or damaged mating surfaces.Thoroughly inspect and clean both the O-ring and the groove/gland before installation.

Common Applications

  • Aerospace fluid and gas systems
  • High-pressure hydraulic systems
  • Chemical processing equipment requiring inert seals

⚠️ Engineering Warnings

  • Verify material compatibility with all system fluids and operating temperatures.
  • Avoid stretching the O-ring beyond its elastic limit during installation.
