Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the assembly, which can pinch or cut the O-ring.Tighten fasteners to the manufacturer's recommended torque specifications.
Using the wrong lubricant, which can degrade the silicone material.Always use lubricants specifically recommended for silicone O-rings and the operating environment.
Installing a twisted or damaged O-ring, leading to immediate leaks.Visually inspect the O-ring before installation and ensure it is seated flat in the groove.

Common Applications

  • Chemical processing equipment
  • Food and beverage production lines
  • Pharmaceutical manufacturing systems
  • High-temperature fluid handling

⚠️ Engineering Warnings

  • Ensure compatibility of the silicone material with all chemicals and media in the application.
