Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-stretching the O-ring during installation.Gently seat the O-ring without distorting its cross-section beyond its elastic limit.
Using an O-ring with inadequate chemical resistance for the application fluid.Verify the material compatibility (Buna-N in this case) with the specific fluid and operating temperature.

Common Applications

  • Hydraulic systems
  • Automotive fluid seals
  • General industrial machinery

⚠️ Engineering Warnings

  • Not recommended for use with ozone, strong acids, or polar solvents.
  • Exposure to UV light can degrade Buna-N material over time.
