Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the O-ring during installation, causing deformation or damage.Install the O-ring with just enough tension to seat it properly in the groove. Avoid excessive stretching.
Using an O-ring in an application where the fluid or temperature exceeds Buna-N's capabilities.Verify the chemical compatibility and temperature range of Buna-N against the specific application requirements before selection.

Common Applications

  • Hydraulic systems
  • Pneumatic systems
  • Oil and gas equipment
  • Automotive components

⚠️ Engineering Warnings

  • Not suitable for exposure to ozone, UV, or weathering conditions.
  • Avoid use with ester-based hydraulic fluids and ketones, as Buna-N exhibits poor resistance to these substances.
