Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong O-ring size.Always verify the required O-ring dimensions (ID, OD, CS) against the groove specifications before installation.
Overtightening the component, leading to O-ring compression.Tighten fasteners to the manufacturer's recommended torque specifications to prevent excessive O-ring deformation and premature failure.
Using sharp tools during installation.Employ plastic or rubber installation tools to prevent nicks and cuts on the O-ring surface.
