Installation Instructions
Installation should be carried out by accepted plumbing practices and the
instructions provided in this manual. However, it is important for the
installer to also be aware of local authority codes and by-laws relevant to
plumbing, which take precedence over these guidelines in any area where they
vary.
Forming Stability
The DuoPEX Gas pipe will remain stable after bending, thanks to the aluminum
layer. This characteristic allows for prefabrication of assemblies before
delivery to the site in many cases.
Minimum Bending Radii
Bending can be done manually, but if tighter bends are required, bending tools
may be used. The minimum bending radii for different nominal diameters are as
follows:
Nominal Diameter (da x s)| Bending Radius (R) without aid| Bending Radius (R)
with bending spring| Bending Radius (R) with bending tool
---|---|---|---
16 x 2.0| 5 x da| 2.0 x da| 3.6 x da
20 x 2.0| 5 x da| 2.0 x da| 3.6 x da
26 x 3.0| 5 x da| 3.0 x da| 4.0 x da
32 x 3.0| 5 x da| 3.6 x da| 4.0 x da
40 x 3.5| 5 x da| 3.6 x da| 4.0 x da
50 x 4.0| 5 x da| 4.0 x da| 4.5 x da

Thermal Changes in Length
- Heating and cooling cause pipe length changes.
- The coefficient of expansion of DuoPEX Gas composite pipes is 0.026 mm/m x k.
- For further information on Linear Expansion Tables and other expansion bend examples contact your DuoPEX representative.
Example Temperature|
---|---
Differential Δ T| 50 k
Pipe length L| 5 m
Coefficient of expansion a| 0.026 mm/m.K
Linear expansion Δ L| 6.5 mm
Δ L| = a x L x Δ T
= 0.026mm/m.K x 5 m x 50 K
= 6.5 mm
Thermal conductivity = 0.45 W/M x K
Fire and Excessive Heat
- Keep DuoPEX Gas pipe a minimum of 500mm from sources of high heat,PEX such as heating appliances and flues from heating appliances
- Keep DuoPEX Gas pipe 1500mm from slow combustion type stoves and flues used to heat hot water or cooking (wet back type)
- Leave 300mm minimum space between DuoPEX Gas pipe and light fittings or other electrical fixtures
- DuoPEX Gas pipe should not be positioned within 150mm of gas or central heating vents or flues
- Where fire collars or the like are required, installers should contact the manufacturer of those products to ensure they have certification for MLP construction
Resistance
UV Resistance
DuoPEX Gas pipes must be protected against direct sunlight or UV radiation.
Consequently, DuoPEX Gas pipes must be covered during transport or storage if
they have been removed from their original packaging. When DuoPEX Gas pipes
are used in a protective sleeve, adequate UV protection is assured during the
installation phase. Furthermore, jackets made from insulating material can
undertake the function of UV protection with DuoPEX Gas pipes. See DuoPEX Gas
product list in this manual for appropriate sleeving.
- It is best practice to ensure that piping is installed out of direct sunlight – protected or not protected.
Chemical resistance
The chemical properties of polyethylene are significantly improved by cross-
linking. Multi-layer pipe with cross-linked polyethylene has been approved for
use in AS/NZS 5601. This includes Natural Gas and LPG. For specific gases
other than
these, please contact your DuoPEX representative.
DuoPEX Gas pipes are resistant to the following media:
- Concrete, plaster, mortar and cement
- Disinfectants and cleaning agents according to DVGW worksheet W 291 and DIN 2000
- All natural potable water constituents
- Corrosion – protection agents according to DIN 1988 Part 4
DuoPEX Gas pipes must be protected against:
- Direct contact with bitumen or bitumen strips
- Greases, solvents and oils
- Contaminated areas as defined by AS/NZS 5601 and AS/NZS 3500
If the DuoPEX Gas system is used in areas where, for example, aggressive gases, permanently acting moistures or building materials containing chlorine are to be encountered, the fittings must be protected using suitable jacketing. It is also best practice to protect fittings with suitable jacketing when in contact with screed, concrete, mortar, plaster or burial in contaminated soil.

DuoPEX Gas Fittings
DuoPEX Gas fittings are manufactured from dezincification resistance (DR) brass with a stainless steel crimp ring and joined to the pipe using a precision and specific crimping tool. To increase joint performance all DuoPEX Gas crimp fittings are characterised by a plastic holding ring which has three important functions:
- As a locating ring that matches the DuoPEX Gas jaws for a perfect crimp position
- It allows the installer to visually check when the pipe is correctly fitted on the fitting
- The fitting has a yellow plastic holding ring to identify the fitting is for gas installations only
The DuoPEX Gas fittings and DuoPEX Water fittings have different O-Ring compositions that are specific to their purpose. The yellow holding ring indicates O-Rings for gas and the blue holding rings indicates O-Rings for water. Use the correct fitting for each application. This must be strictly adhered to.
DuoPEX Gas fittings are available for DuoPEX Gas in sizes ranging from 16mm to 63mm. DuoPEX Gas crimp fittings are classified as a permanent joint under AS/NZS 5601. Pipe and fittings are joined and sealed thanks to the stainless steel crimp ring mechanical deformation (2). This deformation is achieved by using the special DuoPEX Gas jaws.
- Multi-Layer Pipe
- Stainless Steel Crimp Ring
- O-Rings
- Plastic Sight Ring
- DR Brass Fitting
The Plastic Sight Ring aids in locating the jaws in the correct crimp position and features a witness hole to check the pipe has been fully inserted in the fitting.
Making A Joint
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, precautions, and the proper use of this tool. The following describes, in general terms, the jointing procedures but should not be regarded as a substitute for reading and applying the detailed instructions contained in the tool manual.
- Ensure that the battery is fully charged and attach it to the tool.
- Select the jaw size to suit the fitting to be crimped. The jaws must be examined in terms of possible damage or dirt in the compression area.
- To change the jaw, push the pin in, turn pin to unlock and slide the jaw out.
- Insert the jaws and line up the holes in the tool with the hole in the jaw.
- Push the pin through the hole in the jaw and turn pin to lock.
- Cut the pipe to the required length with the recommended multi-layer pipe cutters.
- Insert the approved calibrating/deburring tool into the pipe, and then alternately turn in a clockwise and in a counter-clockwise direction. Ensure that a consistent, smooth chamfer is formed on the end of the pipe.
- Insert the pipe into the fitting and under the stainless steel ring. Push the pipe until it is visible in the slots of the plastic sight ring (witness hole). This ensures you have pushed the pipe home.
- By squeezing the back of the jaw, the jaws will open. If you look at the machined profile on the inside of the jaws you will note a slot on each side of the profile.
- With the jaws open, 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 and the piston has retracted back into the body of the tool.
- Press the back end of the jaws and remove the completed joint.
Product List
Lay Flat UV Sleeving is available in 32mm to 63mm. This sleeving has a maximum UV life of 4 years and should be replaced prior to that time. It is best practice to ensure that piping is installed out of direct sunlight – protected or not protected.
