Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening during assembly, leading to O-ring extrusion or damage.Follow specified torque values for retaining hardware. Hand-tighten where appropriate and rely on the O-ring's compression for sealing.
Using incompatible lubricants or cleaning agents that degrade the silicone material.Consult the material compatibility chart for the silicone elastomer and the intended media. Use only approved lubricants and cleaning solutions.

Common Applications

  • Chemical processing equipment
  • Food and beverage machinery
  • Pharmaceutical manufacturing
  • Automotive sealing systems

⚠️ Engineering Warnings

  • Ensure the O-ring material is compatible with the specific media and operating temperatures.
  • Avoid exposure to ozone, UV radiation, or certain strong acids and bases, which can degrade silicone.
