Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong O-ring size for the groove, leading to overstretching or insufficient sealing.Always verify O-ring dimensions against groove specifications before installation.
Damaging the O-ring during installation by using sharp tools or forcing it into place.Employ a proper O-ring installation tool or use finger pressure to gently guide the O-ring into the groove.
Contaminating the O-ring or the sealing surface with dirt, debris, or incompatible lubricants.Ensure all components are clean and free of contaminants before and during installation.
