Alumaseal
™
Ferrules Eliminate
Sealing Compromises
Tired of leaking fittings? Want a ferrule that seals every time?
These new aluminum ferrules combine the sealing ease of graphite with
the security and reliability of metal ferrules.
PEAK PERFOR ERS
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 550ºC.
Alumaseal
™
ferrules will not allow oxygen to perme-
ate into the system, and do not require retightening
after temperature cycles, making them ideal for
GC/MS applications. They can be used with any stan-
dard
