Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overstretching the O-ring during installation.Stretch the O-ring only enough to clear the retaining lip. Excessive stretching reduces its lifespan and sealing capability.
Using a lubricant incompatible with Buna-N.Always use lubricants specifically recommended for Buna-N to prevent material degradation and premature failure.
Installing on a dirty or damaged groove.Thoroughly clean and inspect the groove for any nicks or burrs before installation to ensure a proper seal.
