Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring damage or deformation.Apply gentle, even pressure during assembly. If resistance is encountered, re-inspect the O-ring and sealing surfaces.
Incorrectly selecting an O-ring material for the specific fluid or temperature environment.Verify the chemical compatibility and temperature range of Buna-N against the intended application fluids and operating conditions.

Common Applications

  • Hydraulic Systems
  • Pneumatic Actuators
  • Fluid Transfer Pipelines

⚠️ Engineering Warnings

  • Ensure Buna-N compatibility with all media to prevent premature degradation.
  • Avoid exposure to ozone, UV light, or high temperatures beyond the material's rated limit.
