SS Fittings and Ferrules
Silcosteel
i
s a patented process where a film of fused silica is vacuum deposited onto SS surfaces
dramatically improving the inertness to many agressive fluids and reactive componds in sampling
and in chromatograpghy use.
Coated tubing and fittings even extend to anti-corrosion, anti-coking and Ultra High vacuum applications
Silco-treated Swagelok and Parker fittings are available from Restek and a custom coating service of
customer supplied parts is available from SilcoTek ( enquiries to
Chromalytic Tech.

IMPORTANT
-
SS Ferrules must NOT be "Silco-treated"
Ordinary uncoated SS ferrules are perfect when used in a "silco-treated" fitting
but "silco-on silco" will NOT seal
Basically the mating surfaces are like sand-paper on a micron scale
some Applications
High Performance Chromatgraphy
Require absolute minimum of dead-volume effects and maintaining "stream-line" flow
oftern requiring perfect matching of ferrules and fittings - to ensure high column efficiency
