INTRODUCTION

This kit provides the tubing and fittings necessary to

connect an MPG1 pressure controller to either an

RPM4 reference pressure monitor or to a PG7302

piston gauge, and also to a device under test. This

document contains instructions for connecting the

fittings and tubing.

INSTALLATION OF INTERCONNECTIONS

Remove Plugs from MPG1 and RPM4 or

PG7302: Unscrew the glands from the test ports

of the MPG1 and RPM4 or PG7302. Remove the

collar and plug from inside each gland.

should be two plastic plugs and one stainless steel

plug. The plastic plugs will not be used. Keep the

stainless steel plug.

Install glands and collars onto flexible 5 in.

nipples: Slide a gland over a nipple so that the

threads of the gland face outward. Next, screw a

collar onto the nipple by turning it to the LEFT.

Allow two nipple threads to show between the

collar and nipple tip.

RPM4 – Install glands and collars onto the 6 in.

nipple.

PG7302 – Install glands and collars onto the

12 in. nipple.

Install nipples into three way tee: Install the 5 in.

nipple into the center port of the three way tee.

Install either the 6 in. or 12 in. nipple into either of the

end ports on the three way tee as shown in Figure 1.

NO.

Tighten the nipples with a 5/8 in. wrench or crescent

wrench. The thick nipple on the right connects to the

MPG1. The thin nipple in the center of the plug

connects to the RPM4 or to the PG7601. In Figure 1

the left port is currently plugged, but the remaining

thin 5 in. nipple can go in the left port and connect to

the DUT.

Figure 1: Two nipples installed in 3-way tee.

Optional: Extend the front feet on RPM4: The front

feet of the RPM4 can be extended so that the RPM4

is inclined for easier reading and display access.

(10 000 psi) or less have 1/8 in. NPTF test ports.

These ports require the use of one of the DH500F

by 1/8 in. NPTM adaptors. Wrap Teflon

tape around the NPT threads of the adaptor three

times, and install the adaptor into the RPM4.

Install the free end of the center nipple into

RPM4 or PG7302:

should be inserted into the test port of the RPM4 or

PG7302. Screw in the gland loosely by hand. The

nipple can be bent slightly to ensure that nipple

enters straight into the test port. Do not tighten the

gland in the RPM4 or PG7302 yet, since it will be

tightened when the system is primed.
