Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overstretching the O-ring during installation.Install the O-ring without excessive tension, allowing it to fit naturally into the groove. Use appropriate installation tools if necessary.
Using incompatible lubricants or cleaning agents.Always consult the material compatibility chart for both the O-ring and the sealing environment. Use only lubricants and cleaners specifically approved for Viton and the media being handled.

Common Applications

  • Chemical processing equipment
  • Automotive fuel systems
  • Aerospace hydraulic systems
  • Oil and gas exploration machinery

⚠️ Engineering Warnings

  • Ensure compatibility of the Viton material with all process chemicals and operating temperatures.
  • Avoid prolonged exposure to steam or hot water, which can degrade Viton over time.
