Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Installing a dry O-ring, leading to tearing or snagging during insertion.Always lubricate the O-ring and groove with a compatible lubricant before installation.
Twisting the O-ring during installation, which can create a leak path.Ensure the O-ring is laid into the groove without any twists or kinks.
Using the wrong lubricant, which can degrade the Buna-N material.Consult material compatibility charts to select a lubricant specifically designed for Buna-N and the operating environment.

Common Applications

  • Hydraulic and pneumatic systems
  • Chemical processing equipment
  • Aerospace and automotive sealing

⚠️ Engineering Warnings

  • Ensure compatibility of the O-ring material with all media and operating temperatures.
  • Do not exceed the recommended pressure or temperature limits for Buna-N seals.
