Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring damage or deformation.Apply gentle, controlled pressure. Lubricate mating surfaces with a compatible lubricant if necessary, and use appropriate tools for installation in tight spaces.
Selecting an O-ring material incompatible with the operating environment (e.g., chemicals, temperature).Consult chemical compatibility charts and temperature range specifications for silicone and 304 stainless steel to ensure suitability for the intended application.

Common Applications

  • High-temperature fluid sealing
  • Chemical processing equipment
  • Food and beverage production lines

⚠️ Engineering Warnings

  • Ensure compatibility of the silicone elastomer and 304 stainless steel with all media and environmental conditions.
  • Avoid exposure to ozone, UV radiation, and certain strong acids or bases unless specifically rated for such conditions.
