Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to nicks or cuts on the O-ring surface.Gently stretch and maneuver the O-ring into place, utilizing lubrication if necessary. Ensure mating surfaces are smooth and free of burrs.
Incorrect O-ring size leading to either extrusion or inadequate sealing.Verify that the O-ring's internal diameter, external diameter, and cross-section precisely match the groove dimensions as per engineering drawings.

Common Applications
