Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the gland, which can lead to O-ring extrusion.Tighten the gland to the manufacturer's specified torque or compression limits.
Using incompatible lubricants, which can degrade the silicone material.Always use lubricants recommended for silicone O-rings and the specific application environment.
Installing the O-ring with sharp tools or excessive force, causing nicks or cuts.Use plastic or rubber installation tools and apply gentle, consistent pressure.

Common Applications

  • Chemical processing equipment
  • High-temperature fluid handling systems
  • Pharmaceutical manufacturing seals

⚠️ Engineering Warnings

  • Verify material compatibility with all media and operating temperatures.
  • Do not exceed the rated pressure or temperature limits of the O-ring.
