Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Incorrect O-ring size selection leading to leaks or extrusion.Verify the groove dimensions and select an O-ring with the precise ID, OD, and CS that matches the application's requirements.
Using excessive force during installation, causing damage to the O-ring.Apply gentle, even pressure during installation. Utilize appropriate tools and techniques, and ensure proper lubrication of the O-ring and groove.
Installing into a dirty or damaged groove, compromising seal integrity.Thoroughly clean and inspect the mating groove for any imperfections before attempting installation. Address any damage or debris.

Common Applications

  • Chemical Processing Equipment
