Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening fasteners which can deform the O-ring and compromise the seal.Tighten fasteners to the manufacturer's specified torque values. Use a torque wrench for accuracy.
Using the wrong size O-ring for the groove, leading to leakage or premature failure.Verify the O-ring's dimensions (ID, OD, CS) against the groove specifications and mating part dimensions before installation.

Common Applications

  • High-temperature fluid systems
  • Corrosive chemical processing
  • Food and beverage processing equipment

⚠️ Engineering Warnings

  • Ensure compatibility of the 304 stainless steel with the specific media being sealed, especially highly aggressive acids.
  • Avoid sharp tools or abrasive materials during installation to prevent nicks or cuts on the O-ring surface.
