Ten O-Ring Tips

  1. Keep O-Rings packaged until installation.
  2. Don't store O-Rings near heat.
  3. Protect O-Rings from UV rays.
  4. Remove old O-Rings with brass or plastic picks to prevent groove damage.
  5. Don't reuse O-Rings.
  6. Clean the seal groove before installation.
  7. Don't soak O-Rings.
  8. Don't twist or cut O-Rings during installation.
  9. Don't select O-Rings based on material color. There is no universal color standard.
  10. Maintain your cooling system. High fluid temperatures are the number-one cause of shortened seal life.
