Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening or excessive stretching during installation.Install the O-ring without undue tension. Verify it sits flush within its groove before full assembly.
Contamination of sealing surfaces or the O-ring itself.Thoroughly clean all mating surfaces and the O-ring prior to installation. Use appropriate, non-petroleum-based lubricants if necessary and compatible.

Common Applications

  • Automotive fluid and fuel systems
  • Aerospace pneumatic and hydraulic seals
  • Medical equipment sealing
