Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size O-ring, leading to leaks or premature failure.Verify O-ring dimensions (ID, OD, CS) match the groove specifications precisely.
Overstretching or twisting the O-ring during installation, causing damage and compromising the seal.Install the O-ring without excessive force or deformation, allowing it to seat naturally in the groove.
Installing on a dirty or damaged groove, which can lead to leaks and O-ring damage.Thoroughly clean and inspect the sealing groove for any imperfections before installation.

Common Applications

  • Hydraulic Systems
  • Pneumatic Actuators
  • Fluid Power Equipment

⚠️ Engineering Warnings

  • Ensure material compatibility with the fluid or gas being sealed.
