  • Specifically developed to overcome the problems associated with the use of 100% graphite and composite ferrules.
  • Strong seal on capillary columns.
  • Leak free - The ferrule and nut expand and contract at the same rate eliminating any chance of leaks with temperature cycling.
  • Nut does not need retightening after initial temperature cycles.

Suitable uses:

  • Ideal for MS interfaces and advanced flow technology due to leak-free


  • Over-tightening of the seal can introduce leaks into the system. Follow the recommended installation instructions to avoid this problem.
