Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong lubricant, which can degrade the Buna-N material.Always consult the material compatibility chart for Buna-N and select a lubricant specifically recommended for this elastomer.
Over-stretching or twisting the O-ring during installation.Handle the O-ring with care, install it with minimal stretching, and ensure it lies flat within the groove without any twists or deformations.

Common Applications

  • Hydraulic cylinders and pumps
  • Pneumatic systems
  • Fuel and oil handling equipment

⚠️ Engineering Warnings

  • Not recommended for applications involving ozone, strong acids, or ketones, as Buna-N exhibits limited resistance to these substances.
  • Ensure operating temperatures remain within the recommended range for Buna-N to maintain sealing integrity.
