Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overstretching the O-ring during installation.Gently stretch the O-ring just enough to fit over the component or into the groove, minimizing stress.
Installing on dirty or damaged mating surfaces.Thoroughly clean and inspect both mating surfaces for any nicks, burrs, or contaminants before installation.
Using incompatible lubricants or sealants.Consult the material compatibility chart for Buna-N and use only recommended lubricants or sealants.

Common Applications
