Installation of Regulator Kit

onto 1/4 in. molstic-S™

Mounting Platform

P/N 401880

Instruction Sheet

This kit is used to upgrade 1/4 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.

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.

PREPARING THE REGULATOR FOR

INSTALLATION

Place a new VCR

®

gasket (P/N 102183) into the inlet

port of the regulator.

Place the VCR male nut (3) over the tube adaptor (2)

and thread it into the regulator inlet port and tighten

finger-tight.

Over-tightening VCR connections will damage

the sealing beads and possibly cause system

leakage. Do not re-use metallic VCR gaskets.

Hold the regulator stationary, and tighten the male nut

1/8 turn past finger-tight.

Install the quick connect body (1) onto the tube fitting

and tighten 1-1/4 rotations beyond finger-tight.

Place a new VCR gasket into the outlet port of the

regulator.

Thread the VCR male union (4) into the regulator outlet

port and tighten finger-tight.

Hold the regulator stationary, and tighten the male union

1/8 turn past finger-tight.

 Attach the regulator mounting bracket to the base of the

regulator using the two included #10-32 socket head 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 VCR coupler (5) as the

molstic interface. Retain the adaptor for future use.

The VCR gaskets are for one-time use and should

therefore be discarded.

Using a pair of properly sized wrenches remove the VCR

coupler and filter as an assembly (5 and 6) from the

female VCR swivel nut (7). Discard the VCR gasket.

Place a new VCR gasket securely against the sealing

surface inside the female VCR coupler (5) of the

molstic-S inlet fitting.

Tighten the VCR coupler and filter subassembly to the

regulator outlet fitting 1/8 turn past finger-tight.

Place a new VCR gasket securely against the sealing

surface inside the female VCR swivel nut (7).

Place the regulator with its bracket on top of the molstic-S

platform. Align the filter assembly’s male VCR outlet

fitting with the mating female VCR swivel nut and thread

the nut onto the fitting.

Hold the filter assembly stationary with a backup

wrench. Tighten the female nut 1/8 turn past finger-

tight.
