This adaptor kit is for making flowpath connections
between the 1/4 in. VCR fittings of a molbloc, molstic,
or a metering valve kit, and devices with 1/4 in.
Swagelok type connections. The kit may be used in
combination with other adaptors to connect to
devices with fittings such as NPT or AN-type fittings.
This kit includes enough adaptors to connect to both
the inlet and outlet of one molbloc, or the outlet side
of at least two molblocs, molstics or metering valve
kits.
INSTRUCTIONS
When Using a molstic (without metering valve kit):
A low or mid flow molstic has a 1/4 in. VCR female
outlet fitting. The high flow molstic outlet is normally
1/2 in. VCR, but the molstic comes with an adaptor so
that its outlet can also be 1/4 in. VCR female. Use the
adaptor kit to connect to a molstic in one of the
following ways:
•
Use the 4VCR gland with VCR male nut to
connect to the molstic’s 1/4 in. VCR female outlet
fitting.
A device with a 1/4 in. Swagelok fitting can be
connected directly to the tube end of the gland
using the 1/4 in. Swagelok nuts and ferrules.
•
Connect a device to the molstic using a 1/4 in. tube.
First connect the 4VCR M x 1/4 in. SWG adaptor
to the molstic outlet fitting. The tube will thread
onto the Swagelok end of the adaptor using the
1/4 in. Swagelok nuts and ferrules.
•
To reduce the overall length and volume of the
adaptors on a low or mid flow molstic, you may
replace the molstic’s 1/4 in. VCR female union with
either the 4VCR F x 1/4 in. SWG adaptor, or the
4VCR gland with a VCR female nut. These two (2)
adaptors will connect to either a Swagelok tube, or
a Swagelok threaded tip, respectively.
When Adapting from a Metering Valve Kit:
Like the low and mid flow molstics, both the low and
mid/hi flow metering valve kits have a 1/4 in. VCR
female union at their outlet. Follow the instructions for
adapting from the low and mid flow molstic above.
When Connecting to a molbloc (without molstic):
When a molstic is
not
used, this adaptor kit will
connect a molbloc with 1/4 in. male VCR fittings
directly to devices or tubes with 1/4in. Swagelok
fittings. Depending on what will be connected to the
molbloc, adapt to both the inlet and outlet of the
molbloc in one of the following ways.
•
Use both 4VCR glands with both VCR female
nuts.
•
Use a combination of one (1) VCR gland with VCR
female nut and the 4VCR F x 1/4 in. SWG adaptor.
