Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring nicks or tears.Apply lubricant and gently maneuver the O-ring into place. If resistance is met, reassess the installation path or O-ring size.
Incorrect O-ring size selection, resulting in improper compression or leakage.Always verify the groove dimensions and O-ring specifications against the design requirements before installation.
Installing the O-ring dry in a dynamic application, causing premature wear.Lubricate O-rings for dynamic applications with a compatible, non-exuding lubricant to reduce friction and wear.
