Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Incorrect O-ring size selection leading to leakage or over-compression.Verify and re-verify all critical dimensions (ID, OD, CS) against the mating groove specifications before ordering and installation.
Damaging the O-ring during installation due to sharp tools or improper handling.Use only clean, non-metallic installation tools. Ensure the groove chamfers are smooth and free of burrs.

Common Applications

  • Hydraulic systems
  • Pneumatic systems
  • Chemical processing equipment
  • Automotive sealing
