Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-stretching the O-ring during installation.Install the O-ring without excessive tension. For larger O-rings, consider a 'figure-eight' or 'twist' installation method.
Using incompatible lubricants or cleaning agents.Always consult the material compatibility chart for Buna-N and the specific fluid media being sealed. Use only recommended lubricants.

Common Applications

  • Hydraulic Cylinders
  • Pneumatic Systems
  • Fluid Power Manifolds

⚠️ Engineering Warnings

  • Not recommended for use with strong oxidizing acids or ketones.
