Product Description

EZIPRESS Water, Gas & Solar Solutions

 

Overview

The EZIPRESS™ system provides a complete press fit system for copper tube with specific fitting ranges for Water, Gas and Solar applications.
No more brazing, soldering or flaring required. All joints are simply assembled with a pressing tool for a quick, neat and secure result first time, every time.


The EZIPRESS™ system incorporates a dual indicator system to help minimize user error during installation. The first part of
this system is the “Press Indicator Coating” which is applied to the outside of each fitting. The second part is the “Leak Path Design O-ring” which allows un-pressed joints to leak during the pressure test phase of installation.
Covering size ranges from DN15 to DN100 with a broad range of fittings available, you’ll notice the cost savings on your first job.


The EZIPRESS™ product range is manufactured from high quality copper and DZR brass material and is factory-fitted with either a yellow HNBR sealing element for gas applications, a
black EPDM sealing element for water applications and the latest addition to the range, a red FKM sealing element for solar water applications.
All installations should be carried out by an appropriately licensed tradesperson, in full accordance with the EZIPRESS™ installation guidelines, in accordance with the relevant Australian standards and any additional local authority
requirements. When installed subject to the above conditions the EZIPRESS™ system will provide years of trouble free service.
EZIPRESS™ is a complete solution for all water, gas and solar applications.

 

Application

Traditional methods for joining copper tube have previously involved heating or flaring of the tube which can be both dangerous and time consuming.
The EZIPRESS™ system uses a pressing tool to produce a secure joint in a minimal amount of time. The pressing method guarantees a perfect seal every time and eliminates the need for call backs to repair partially welded joints, etc.

Installation Considerations

EZIPRESS™ Gas should always be installed in compliance with AS/NZS 5601. EZIPRESS™ Water & Solar fittings should always be installed in compliance with AS/NZS 3500.
All installations should be by appropriately licensed tradespeople, in full accordance with the EZIPRESS™ installation guidelines, the relevant Australian standards and any additional local authority requirements. Most installation requirements can be sourced from this document.

Copper Tube Cutting

It’s 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 EZIPRESS™ fitting.

Working Pressure

EZIPRESS™ Gas is suitable for use in applications covered by AS/NZS 5601, where all consumer piping is restricted to 200kPa maximum pressure. All EZIPRESS™ water, solar and gas fittings have been tested to a maximum operating pressure of 1600kPa.

Protection of Sealing Element
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 fitting
  • Ensuring the ring is well lubricated
  • Ensuring the ring is not contaminated by any foreign material

Connection to Other Materials

EZIPRESS™ is suitable for connection to most existing pipe work systems by utilizing our range of EZIPRESS™ threaded adaptors. When installing an EZIPRESS™ threaded adaptor, it is recommended that the threaded connection be installed first, before performing the pressing operation. It is important that the
spanner flats on the fittings are used rather than gripping the tube section of the fitting.

Minimum Clearances

When installing two EZIPRESS™ fittings in close proximity to one another, it’s essential that a minimum clearance 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 fittings:

Nom Size Minimum Clearance (mm)
DN15 - 5
DN20 - 5
DN25 - 5
DN32 - 15
DN40 - 20
DN50 - 20
DN65 - 20
DN80 - 20
DN100 - 20

When an EZIPRESS™ fitting is being installed close to an existing brazed fitting, the clearances in the following table need to be observed. This will ensure that the press fitting is kept clear of tube that may have been excessively annealed during the brazing
process.

Nom Size Minimum Clearance (mm)
DN15 - 10
DN20 - 10
DN25 - 15
DN32 - 15
DN40 - 20
DN50 - 20
DN65 - 20
DN80 - 20
DN100 -20

Brazing close to EZIPRESS™ fitting joints should be avoided as the heat generated by the process can damage the seals of the fitting. 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.

Nom Size Minimum Clearance(mm)
DN15 400
DN20 500
DN25 700
DN32 900
DN40 1000
DN50 1300
DN65 1700
DN80 2100
DN100 2600

Protection From Physical Damage
Due care should be taken to protect EZIPRESS™ fittings from any mechanical or chemical damage both prior to, during and after installation.
Where EZIPRESS™ fittings 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 EZIPRESS™ fittings and copper tube from abrasion.

Clipping
All EZIPRESS™ fittings should be clipped by way of a recognized fixing which complies with the requirements of AS/NZS 5601 for gas applications or AS/NZS 3500 for water and solar applications. Fixing spacing should be observed for both horizontal and vertical pipe runs as outlined on the table below.

Nom Size Vertical or Horizontal Run Spacing (m)
DN15 1.5
DN20 1.5
DN25 2.0
DN32 2.5
DN40 2.5
DN50 3.0
DN65 3.0
DN80 3.0
DN100 4.0

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.

Chases, In-Slab, Under-floor
Where EZIPRESS™ fittings 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.
