One piece fused silica adapter
(FS)
The one piece FS adapter, essentially a reducing ferrule, is recommended for use in fittings where the
polyimide ferrule will not be removed. Connections are made and disconnected by loosening the
fitting nut and sliding the tube out.

Polyimide adapters can
be used at temperatures
up to 350°C.
PEEK adapters are not
recommended for use
above 175°C.
tech tip
If a fused silica tube
breaks off in a through-
type union, remove
the nuts and the tube
opposite the broken
one. Clear the fitting by
passing a drill or wire of
the appropriate diameter
into the unbroken side
and through the center
of the fitting.
Our

kit

remove ferrules from
all types of fittings.
tech tip
Virgin polyimide adapters
are effective electrical
insulators, making them
the ideal choice for
capillary electrophoresis.
Virgin polyimide is
produced as Vespel
®
.
Fused silica adapters are available in
Valcon polyimide for use up to 350°C
and in PEEK for lower temperature
applications (up to 175°C). Valcon
polyimide is a unique graphite-
reinforced composite, specially
prepared to maximize mechanical
stability at high temperatures. Small
blocks are subjected to extreme loads
by a process known as hot isostatic
pressing, with individual ferrules
Ferrule removal kit
These tapered tools have teeth designed to grip and
remove fused silica adapters if they get stuck in a fitting
detail. Each kit has two sizes of tools, so they can retrieve
1/32" and 1/16" adapters.

subsequently machined from these
blocks. The result of this two-step
process is a fused silica adapter with
high temperature stability which far
exceeds that of parts produced by
conventional molding. Note that the
determining factor in adapter size
selection is the fused silica tubing’s
outer diameter, or OD. Typical ODs
for common columns are included
in the product number tables.
