The AUPURIT™ A+ Press (Copper) system provides a complete press t
system for copper tubes with size ranges from DN15 to DN100 and broad
range of ttings for water and gas applications.
• Traditional installation methods like brazing, soldering or aring are no longer
required. All joints are simply assembled with a pressing tool for a quick,
consistent, and secure result every single time
• Incorporates a dual indicator system to help minimise errors during installation:
• “Press Indicator Coating” which is applied to the outside of each ttings.
• “Leak Path Design O-ring” which allow tradesmen to detect un-pressed
joints during the pressure test phase.
• Black EPDM seals for water application
• Yellow HNBR seals for gas application
• Manufactured from high quality copper and DZR brass in compliance with AS
1432 and AS 3688
All installations are to be carried out by licensed tradesperson and in full
accordance with the AUPURIT™ A+ Press (Copper) installation guidelines, relevant
New Zealand standards, and any additional local authority requirements. When

will provide years of trouble-free service.
Overview

Technical Manual
2www.aupurit.co.nz
The AUPURIT™ A+ Press (Copper) system uses pressing tool to produce a secure
joint in a minimal amount of time. The crimping method produces a consistent
level of compression around the full circumference of the crimp ring, guaranteeing
a perfect seal every time.
Gas ttings shall be installed in accordance with AS/NZS 5601 for gas
applications including:
• Natural Gas
• Liquid Propane Gas (L.P.G)
Water ttings shall be installed in accordance with AS/NZS 3500 for water
applications including:
• Hot and Cold Potable Water
• Grey Water
• Waste and Drainage
For optimum installation results, please take time to familiarise with the installation
considerations outlined on Pages 7-11 in this technical manual.

sealing element.
EPDM is a synthetic rubber product
that is strong and exible, resists decay
and provides good resistance to aging,
ozone, sunlight, weathering and hot
water. This makes it ideal for seals in
a broad range of applications. It is

The AUPURIT™ A+ Press (Copper)
ttings have a water leak path
design on the sealing ring where the
water will leak from the tting until
the pressing operation is completed
adequately. Testing is suggested to
be at 200-300kPa to enable the leak
function to operate successfully.

Installation
Considerations
It is recommended that copper tube
should only be cut with a wheel-type
tube cutter. To prevent damage to the
sealing ring, it is essential to deburr
both the inside and outside of all
copper tube prior to insertion of any
AUPURIT™ A+ Press (Copper) tting.
AUPURIT™ A+ Press (Copper) Gas is
suitable for use in applications covered
by AS/NZS 5601, where all consumer
piping is restricted to 200kPa maximum
pressure.
All AUPURIT™ A+ Press (Copper) Water
and Gas ttings have been tested
to a maximum operating pressure of
1600kPa.
The sealing element is critical to the
integrity of the joint. Care should
be taken to protect it from damage.
Simple precautions include:
• Ensuring the seal ring is properly
located in the tting,
• Ensuring the ring is well
lubricated, and
• Ensuring the ring is not
contaminated by any foreign
material.
AUPURIT™ A+ Press (Copper) Gas should always be installed in compliance with
AS/NZS 5601. AUPURIT™ A+ Press (Copper) Water should always be installed in
compliance with AS/NZS 3500.
All installations should be carried out by appropriately licensed tradespeople, in full
accordance with the AUPURIT™ A+ Press (Copper) installation guidelines, the relevant
Australian standards and any additional local authority requirements. Most installation
requirements can be sourced from this document.

AUPURIT™ A+ Press (Copper) is
suitable for connection to most existing
pipe work systems by utilizing our
range of A+ Press (Copper) threaded
adaptors. When installing an A+
Press (Copper) threaded adaptor, it
is recommended that the threaded
connection be installed rst, before
performing the pressing operation. It is
important that the spanner ats on the
ttings are used rather than gripping
the tube section of the tting.
When installing two A+ Press (Copper)
ttings near one another, it is essential
that a minimum clearance should be
maintained between the two. This
ensures that the tube being pressed is
free of any deformities which might be
caused in the pressing process.
The table below provides the
minimum clearances required
between two ttings:

When an A+ Press (Copper) tting is
being installed close to an existing
brazed tting, the clearances in the
following table need to be observed.
This will ensure that the press tting is
kept clear of tube that may have been
excessively annealed during the brazing
process.
Brazing close to A+ Press (Copper)
tting joints should be avoided as
the heat generated by the process
can damage the seals of the tting. To
ensure that damage is not caused, the
minimum clearances in the following
table should be observed. It’s also
recommended that additional heat
suppression methods are employed to
prevent damage to the joint.

Due care should be taken to protect A+ Press (Copper) ttings from any mechanical
or chemical damage both prior to, during and after installation.
Where A+ Press (Copper) ttings and/or copper tube penetrate timber or metal
framework, appropriate precautions should be taken to protect it from damage.
Holes should be sized to allow for longitudinal movement, expansion and
contraction, whilst still securing the pipe adequately. Suitable grommets or sleeves
should be used in metal frames to protect the A+ Press (Copper) ttings and
copper tube from abrasion.
All A+ Press (Copper) ttings should be clipped by way of a recognized xing
which complies with the requirements of AS/NZS 5601 for gas applications or AS/
NZS 3500 for water applications.
Fixing spacing should be observed for both horizontal and vertical pipe runs
as outlined on the table below.
For pipe work being suspended on rod hangers the minimum diameter of the rod
hanger should be 9.5mm for all tube sizes up to and including 50mm and 12.7mm
up to 100mm.

Where A+ Press (Copper) ttings and
copper tube are installed in chases or
cast in slabs the installation must be in
accordance with AS/NZS 5601 for gas
applications and AS/NZS 3500 for water
applications and/or any other relevant
building regulations or standards.
A+ Press (Copper) Gas ttings can be
installed as an appliance connection
in accordance with AS/NZS 5601,
provided that an appropriate means of
disconnection is incorporated.
All testing should be undertaken
in accordance with AS/NZS 5601–
Appendix E (pressure testing for gas
installations) or AS/NZS 3500 for water
installations in addition to any other
local regulations or requirements.
During testing all joints should be
checked for leaks.
A+ Press (Copper) ttings and copper
tube should be buried with a minimum
cover of 300mm. Bedding/backll
material must be of a type that will not
have an adverse effect on the tube or
ttings. Sand is recommended. Marker
tape should be installed approximately
150mm above the tube. A+ Press
(Copper) ttings should be able to
be installed directly in the trench
without any form of coating. Additional
precautions should obviously be
taken in areas where aggressive soil
conditions are known to exist or where
it may be a requirement of the local
certifying authority.
