Alumaseal? ferrules* combine the advantages of graphite and Vespel®/graphite ferrules, and eliminate the disadvantages, for enhanced performance in any application. 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.
