Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring nicks or tears.Apply a compatible lubricant and use gentle, even pressure during installation, ensuring the O-ring seats properly without stretching or twisting.
Incorrect O-ring size for the groove, resulting in improper sealing or extrusion.Verify the O-ring's dimensions (ID, OD, CS) against the groove specifications to ensure a proper fit and prevent extrusion under pressure.
