Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening during installation, leading to extrusion or damage.Apply only sufficient force to seat the O-ring; it should not be compressed beyond its designed limits.
Using an O-ring incompatible with the fluid or temperature.Always verify the material's chemical and temperature resistance against the operating environment.

Common Applications

  • Hydraulic systems
  • Pneumatic cylinders
  • Automotive sealing
