An extra port block can be placed between modules to provide
two auxiliary 1/4 NPTF ports. Its mounting position can be
rotated to obtain the most convenient operating orientation. If
only one auxiliary port is to be used, the unused port must be
closed with a pipe plug. (The inlet and outlet are not threaded.)
Specially designed clamps provide a quick and easy assembly
or disassembly of MD3
TM
modules. Two allen-head bolts quickly
tighten or loosen the clamp using a 5/32 or 4mm hex key. The
clamp contains a plate carrying two O-rings to provide positive
sealing between modules.

Clamp for Module Connections
Two brackets are normally used to mount an FRL to a vertical
surface. The mounting bracket attaches to the module
connecting clamp (see above) with a single screw. Each bracket
then employs two bolts (1/4” or 6mm) to connect the assembly
to the mounting surface.

Mounting Brackets
Either male or female end ports can be attached to threaded inlet
and outlet lines. This allows all modules of an FRL assembly to
be removed easily and quickly without having to unthread the
end modules. The end ports are attached to the modules with
clamps (see at left). End ports can be included in an assembled
FRL or ordered separately by the following part numbers:
