Alumaseal® Ferrules, Restek
Fittings and Connectors
Alumaseal® ferrules combine the advantages of graphite and Vespel®/graphite ferrules, and eliminate the disadvantages, for enhanced performance in any application.

  • Aluminum construction will not crack or fragment
  • Stable to 550°C
  • Use with any 1/16" compression-type fitting

The unique front and back ferrule design seals easily and surely, the ferrules will not fragment or off-gas, and they are stable to 550°C. Alumaseal® ferrules will not allow oxygen to permeate into the system, and do not require retightening after temperature cycles, making them ideal for GC-MS applications. They can be used with any standard 1/16" compression-type fitting, with fused silica columns. For leak-tight seals, we highly recommend you try Alumaseal® ferrules.
