The modular designs of the MID-SIZE and FULL-SIZE series offer
maximum flexibility in customizing FRL assemblies. As shown at the
right, connector kits are required to interconnect units. Various port
kits (shown below) can be used to connect the assemblies to the
inlet and outlet piping. Note that all FRL components have threaded
ports so that conventional pipe fittings may be used where desired.

Mounting Bracket Kit 915K77
L-shaped metal brackets (not illustrated) are used f or wall mounting
modular assemblies. Kit contains two brackets and four screws for
attaching brackets to tops of modular units.
BANTAM Units
BANT AM modular units use end plates secured with scre ws to hold
the pipe or tubing ports (see below), and also to serve as mounting
brackets. Shor t screws are used to secure the end plates when a

Male and Female End Ports
Either male or female end ports can be attached to threaded inlet
and outlet lines. This allows all modules of an FRL assemb ly 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:

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.
For BSPP threads, add a “W” suffix to the model number,

then employs two bolts (1/4” or 6mm) to connect the assembly
to the mounting surface.
