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 oers 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-eective
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 eectively 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 coecients 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.

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.

Step 4.
For manual tool use,
regularly check with the
gauge supplied by sliding
the opening of the gauge
over the compressed ring. If
the gauge passes over all
parts of the ring without
interference, then the
joint has been crimped
satisfactorily.
Correctly serviced battery
tool do not require a gauge
check if the joint has
been completed as per
instructions.
If the gauge experiences
any interference, the
joint is under crimped.
The tool should then
be adjusted. (See
adjustment instructions
in this manual).
Do not double crimp.
Step 3.
Make sure the tool jaws are
centralised over the crimp
ring at 90° to the joint.
When using the manual tool,
close the tool completely to
compress the crimp ring.
The tool will click at final
compression.
When using a battery tool, ensure the tool has fully closed
and released indicating a completed joint.
32mm Joints
When crimping Auspex
32mm, use the battery
tool with a 32mm DuoPEX
Jaw. Place the fitting inside
the jaws so that the raised
section of the plastic sight
ring fits into the slot in the
jaws. Release the jaws so
they fit snugly over the
fitting, ensuring that the
raised section of the plastic
sight ring is still located in
the slots in the jaw.
Press the switch mechanism until the joint is completed.
Press the back end of the jaws and remove the
completed joint.

10 | Auspex Fire Manual
Pinched Ring
When crimping Auspex fittings, care should be taking to
ensure the tooling is positioned correctly so to not pinch the
crimp ring. Fittings that are damaged in this manner should
be replaced.
Tool Adjustment
Incorrect adjustment can cause under-crimping and failure of
the joint. It is good practise to check tool adjustment regularly.
1. Ensure all moving parts are always kept well lubricated
2. Open the handles fully
3. Using a flat head
screwdriver, loosen (but
don’t fully unscrew) the
locking bolt
4. Using a screwdriver,
rotate the adjusting
screw a quarter turn
clockwise
Manual tools available for copper crimp ring connections
16, 20 and 25mm. Only Auspex approved tools can be
used.
5. The adjusting screw has 4 flat faces in a square shape
for the locking bolt to fix on. Therefore the adjusting
screw must always be vertical or horizontal in orientation
and never at an angle or the locking bolt will damage it
6. Retighten the locking bolt
7. Crimp a new trial joint as a test away from the working
location and test with the gauge
8. If OK, continue to use the tool
If the gauge fails, repeat adjustment until trial crimped joint is
correct. More detailed instructions are included with the tool.
Design the installation in such a way as to not stress the
system joints, bend supports may be required.
Step 5.
Pressure test the system in accordance with
AS/NZS 3500 and with local requirements.

Clips
Pipe clips should be installed so that the pipe can move
freely. Plastic system clips are available, however if using a
non-propriety clipping system, they must be non-metallic
where in contact with the pipe. General cable ties are not
recommended. Any damage caused by non-propriety clips
will not be covered by warranty. Neutral Cure silicon is
permitted in AS/NZS 3500 to protect pipes through
penetrations.

DuoPEX Water System
The DuoPEX Water system is ideal for any large bore piping
required within the 101D project, with 40mm, 50mm and
63mm available. DuoPEX Water oers the versatility and
ease of a WaterMark certified multi-layer pipe system and
can be used in potable water and various other installations.
Advantages of the DuoPEX Water System
1. Form stability during installation, for example in a curve
2. Low thermal conductivity level
3. Light weight during transport and installation
4. Thermal expansion is lower than that of other pipes
5. Lower pressure loss thanks to the smooth inner layer
6. Suitable for Hydronic Heating
DuoPEX Water Fittings
DuoPEX Water fittings are manufactured from dezincification
resistance (DR) brass with a stainless steel crimp ring and
joined to the pipe using a specific precision crimping tool.
DuoPEX Water fittings are available in a full range of
couplings, elbows, tees and conversion fittings.
