Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-stretching the O-ring during installationGently ease the O-ring into the groove, using minimal force to avoid permanent deformation or weakening of the sealing element.
Using incompatible lubricantsConsult the O-ring material compatibility chart for appropriate lubricants to prevent swelling, degradation, or loss of sealing properties.

Common Applications

  • Chemical processing equipment
  • Food and beverage machinery
  • Pharmaceutical manufacturing
  • High-temperature fluid systems

⚠️ Engineering Warnings

  • Ensure operating temperatures and chemical exposure are within the specified limits for silicone and 316 stainless steel.
  • Verify the groove dimensions are correct to prevent O-ring extrusion or premature failure.
