This adaptor kit is for making flowpath connections
between a mid flow or high flow molstic™ or a
mid/high flow metering valve kit and DUTs (devices
under test) having 1/2 in. VCR or 3/8 in. Swagelok
®
connections. The kit can also be used to adapt from
a 1E5 molbloc’s 1/2 in. VCR male inlet and outlet
fittings to 3/8 in. Swagelok when no molstic is used.
INSTRUCTIONS
When Using a High Flow molstic:
The high flow molstic outlet fitting is 1/2 in. VCR female.
•
DUTs with 1/2 in. VCR male fittings can be
connected directly to the available 1/2 in. VCR
female connector on the molstic.
•
To adapt from the molstic’s 1/2 in. VCR female
fitting to a device with a 3/8 in. Swagelok
connection, use an 8VCR gland with an 8VCR
male nut to connect to the molstic and connect
directly to the DUT using 3/8 in. SWG nut and
ferrules on the tube end of the 8VCR gland.
•
To adapt from the molstic’s 1/2 in. VCR female
fitting to a 3/8 in. tube which leads to another
device, connect the tube to the molstic using the
8VCR M x 3/8 in. SWG adaptor.
When Using a Mid Flow molstic (without metering
valve kit):
The mid flow molstic outlet fitting is a 1/4 in. VCR
female union. To connect to devices with larger fittings,
first replace the 1/4 in. union with the 4VCR F x 8VCR F
adaptor. The bracket that supported the 1/4 in. VCR
union must be removed from the molstic using a 3
mm Allen wrench. There is no bracket included to
support the 4VCR F x 8VCR F adaptor. After installing
the 4VCR F x 8VCR F adaptor, connect to other
devices using the high flow molstic instructions
above.
When Adapting from a Mid/High Flow Metering
Valve Kit:
The mid/high flow metering valve kit may be installed
on either a mid flow or high flow molstic. Like the mid
flow molstic, the metering valve kit has a 1/4 in. VCR
female union at its outlet. To connect to devices with
larger fittings, first replace the 1/4 in. union with the
4VCR F x 8VCR F adaptor. The bracket that
supported the 1/4 in. VCR union must be removed
from the molstic using a 3 mm Allen wrench. There is
no bracket included to support the 4VCR F x 8VCR F
adaptor. After installing the 4VCR F x 8VCR F
adaptor, connect to other devices using the high flow
molstic instructions above.
When Connecting to the 1E5 molbloc (without
molstic):
When a 1E5 molbloc is used without a molstic, this
adaptor kit will connect the molbloc’s 1/2 in. male
VCR fittings to 3/8 in. Swagelok devices or
connectors. Use an 8VCR gland with an 8VCR female
nut on each end of the molbloc. Use the 3/8 in.
Swagelok nuts and ferrules for the tube end of each
gland.
