Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overstretching the O-ring during installation.Carefully place the O-ring into its groove without excessive tension to prevent premature failure and loss of sealing integrity.
Using incompatible lubricants or cleaning agents.Always consult material compatibility charts to ensure lubricants and cleaning agents will not degrade the silicone elastomer or the Aluminum 6061 core.

Common Applications

  • Automotive powertrain seals
  • Aerospace fluid systems
  • Industrial machinery and equipment

⚠️ Engineering Warnings

  • Avoid exposure to steam at high pressures, as this can degrade silicone.
  • Ensure the O-ring is not exposed to strong acids or bases, which can damage the silicone elastomer.
