Instruction Sheet
This kit is used to upgrade 1/2 in. single or dual
molstic-S platforms that do not include the integrated
pressure regulator. This upgraded configuration is
ideal for the situation where the device under test
(DUT) will be tested while plumbed downstream of the
molbloc-S.
molstic-S platforms that do not include the integrated
pressure regulator. This upgraded configuration is
ideal for the situation where the device under test
(DUT) will be tested while plumbed downstream of the
molbloc-S.
High pressure gases are potentially hazardous.
Energy stored in these gases can be released
unexpectedly and with extreme force. High
pressure systems should be assembled and
operated only by personnel who have been
instructed in proper safety practices.

cap screws, #10 flat washers, and the #10 lock washers.
The long side of the bracket should be perpendicular to
the direction of flow through the regulator.

INSTALLATION OF REGULATOR ONTO
MOLSTIC-S
Using a pair of properly sized wrenches remove the
VCR x tube adaptor which is on the inlet end of the
molstic-S. This will leave a female VCR swivel nut (7)
as the molstic interface. Retain the adaptor for future
use. The VCR gaskets used in this connection are for
one-time use and should therefore be discarded.
