Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overstretching the O-ring during installation.Gently ease the O-ring into the groove, using a non-metallic tool if necessary, to prevent excessive elongation which compromises sealing performance and lifespan.
Installing into a contaminated or damaged groove.Thoroughly clean and inspect the sealing groove for any debris, sharp edges, or imperfections that could damage the O-ring and lead to premature failure.

Common Applications

  • Hydraulic and pneumatic systems
