Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Stretching the O-ring excessively during installation.Gently ease the O-ring into its groove, using no more force than necessary to avoid permanent deformation and loss of sealing capability.
Installing on contaminated or damaged mating surfaces.Thoroughly clean and inspect all sealing surfaces for nicks, burrs, or foreign particles before O-ring installation to prevent premature failure.
