Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring damage.Apply moderate, even pressure, utilizing appropriate tools if necessary, to avoid pinching or tearing the O-ring.
Incorrect lubrication, causing premature seal failure.Always use a lubricant compatible with both the O-ring material (Buna-N) and the system media.

Common Applications

  • Aerospace hydraulic systems
  • Medical device seals
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Ensure compatibility of system media with Buna-N elastomer.
  • Do not expose to temperatures exceeding the specified operational limits of Buna-N.
