The Auspex Fire pipe and
fitting system provides a
revolutionary solution to meet
new standard requirements in
the fire industry.
From 2019, legislation now requires all residential buildings
4 stories or more to be sprinkler protected. The National
Construction Code oers significant reliability and cost saving
advantages by referencing the new FPAA101D PEX pipe
sprinkler system, which permits sprinklers to be plumbed o
the already required domestic riser.
The PEX pipe “101D” system is by far the most cost-eective
option for installers and developers of these residential
buildings. This eliminates the need to provide dedicated
sprinkler and hydrant service tappings, fire pumps and alarm
equipment. Utilising drinking water supplied by a WaterMark
approved piping system significantly reduces backflow
hazards to the community and now eectively eliminates the
possibility of sprinkler systems being inadvertently shut o.
The Auspex system was used for tests conducted by
CSIRO for the Fire Authorities at the very beginning of the
development of the new FPAA101D system. Since then,
Auspex has continued to work on developing a suite of
dedicated piping and fixing arrangements specifically for
sprinkler head fit o, in all relevant pipe diameters. This
ensures installers have the easiest and fastest means of
fitting o sprinklers in the wall or ceiling that is compliant
with the relevant Codes and Standards.

Auspex Fire Fitting Pressure Drop
Pressure losses due to individual resistances can be
calculated based on the loss coecients and based on the
equivalent pipe lengths of the individual resistances.
These value equivalents are then added to the pipe lengths
of the respective pipe sections to then calculate the
total resistance.

Pressure Losses Due to Individual Resistances
(Auspex Fire Fittings)
a. The symbol "V" for flow velocity defines the location
of the proper reference velocity in the fitting and
connecting piece
b. For reduced tees, the resistance value of the similar tee
is assumed with the smallest dimension of the reduced
tee for the flow path to be calculated
General: The loss coecient is assigned in each case to
the volumetric flow (partial flow), which is indicated in the
diagram with the symbol "V".

Step 1.
Measure the pipe to the
correct length and using a
secateur-type pipe cutter,
cut the pipe squarely and
remove any burrs. The end
of the pipe may need to be
freshly cut to ensure smooth
passage for the fitting.
Do not use a hacksaw.
Step 2.
The pipe is pushed over the
barbed fitting and at the
same time under the crimp
ring. The fit should be firm.
If the joint feels sloppy or
hard to insert, check pipe
and fittings. Do not use
lubricants. Ensure the pipe
is visible in both crimp ring
witness holes.
witness hole
The witness holes should
be completely filled.
Making A Joint
Auspex fittings from 16mm-25mm use a copper crimp ring
connection and can be crimped with an Auspex manual tool
or a Rothenburger battery tool.
It is most important that the tool manual supplied with the
tool is read in its entirety and the user becomes familiar with
the maintenance, calibration and proper use of the tool.
The 32mm Auspex water fitting has a Stainless Steel
crimp ring and can only be crimped with the battery tool
using a DuoPEX jaw (see page 9). The DuoPEX jaws are
universal across all systems shown below.
Auspex 32mm water
fittings are defined by the
clear plastic holding ring
and are for use only with
the single layer Auspex
water pipe and multi-
layer Auspex Gas pipe.
DuoPEX Water
fittings are defined
by the blue plastic
holding ring and are
for use only with the
multi-layer DuoPEX
Water pipe.
DuoPEX Gas
fittings are defined
by the yellow
plastic holding ring
and are for use only
with the multi-layer
DuoPEX Gas pipe.
