Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong lubricant.Always use a lubricant compatible with Buna-N and the specific media being sealed.
Overtightening hardware, causing O-ring compression.Follow recommended torque specifications for hardware to prevent over-compression and premature failure.
Stretching or twisting the O-ring during installation.Handle the O-ring carefully and ensure it sits flat in the groove without deformation.
