Internal reducing ferrule
(ZRF)
Reducing ferrules provide an
inexpensive way to connect small
temporary transfer lines to valves or
fittings designed for larger tubing.
For long term use, we recommend
our reducing unions, internal reducers
(IZRs), or external reducers (EZRs), as
appropriate.
Internal
ZDV (zero dead volume)
reducing ferrules are designed for use
with all standard Valco internal style
fittings – that is, those with a male nut
and female fitting detail. The ferrule
features an integral pilot which fills
the pilot cavity (the space between
the end of the ferrule and the bottom
of the detail), yielding a zero dead
volume fitting.
I
nternal reducing ferrules
Use these ferrules in internal type fitting details, with nuts that have external
threads.

ZDV reducing ferrules are
designed for use with all standard
external style fittings – that is, those
with a female nut and a male fitting
detail. This ferrule has a slightly longer
pilot than the internal version, to
accommodate the longer external
detail. The result is a zero dead volume
fitting. A single groove indicates that
the ferrule has the longer pilot and is
for use in an external detail.
Standard
reducing ferrules can be
used where mixing is not a problem,
such as with liquid or gas delivery. A
1/16" to 1/32" ferrule of this style is
simply a 1/16" ferrule with a 1/32" hole.
tech tip
If you are doing resistive
heating of traps or
columns, note that our
virgin polyimide reducing
ferrules are effective
electrical insulators.
Virgin polyimide is
produced as Vespel
®.
