Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Installing a dry O-ring, leading to tearing or premature wear.Always lubricate the O-ring with a compatible, non-degrading lubricant before installation.
Over-stretching or twisting the O-ring during installation, causing deformation and seal failure.Handle the O-ring with care and ensure it is seated squarely in the groove without excessive force.

Common Applications

  • Hydraulic Systems
  • Aerospace Fluid Connectors
  • Marine Sealing Applications

⚠️ Engineering Warnings

  • Verify material compatibility with the specific fluid or chemical being sealed.
  • Avoid exposure to extreme UV radiation or ozone, which can degrade Buna-N over prolonged periods.
