Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a dry installation which can lead to O-ring damage.Always lubricate the O-ring and the groove with a compatible lubricant before installation.
Overstretching the O-ring during installation, causing permanent deformation.Stretch the O-ring only as much as necessary to fit, and use appropriate tools to avoid undue stress.
Installing a twisted or pinched O-ring, leading to immediate leakage.Visually inspect the O-ring after seating to ensure it is flat and properly seated in the groove without any twists.
