Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the assembly, which can compress and damage the O-ring.Adhere to specified torque values or assembly guidelines to prevent over-compression.
Using incompatible lubricants that degrade the silicone material.Always consult the material compatibility chart for appropriate lubrication.
Twisting or stretching the O-ring during installation, leading to premature failure.Handle the O-ring gently and ensure it is properly seated in the groove without distortion.
