Elson EPS PEX/AL/PEX Gas Pipe — Certified for Australian Gas Installations
EPS Gas PEX pipe is a multi-layer composite pipe designed specifically for gas piping installations. The pipe is constructed with an inner and outer wall of crosslinked polyethylene (PE-Xb) bonded on both sides to an aluminium core — a PEX/AL/PEX structure that combines the flexibility of PEX with the dimensional stability and gas barrier properties of aluminium. The pipe has been tested and approved in accordance with Australian Standard AS 4176.8 under licence number SMKP 21859, and is rated at Class 500 kPa. It is joined using the EPS crimp fitting system — the same fittings used for the EPS water pipe range — and must be installed by a licensed gas fitter in accordance with AS/NZS 5601.

EPS Gas PEX Pipe Range
| Size (DN) | Colour | Class | Standard | Coil Lengths | Clipping Spacing |
|---|---|---|---|---|---|
| 16mm | Yellow (RAL 1033) | 500 kPa | AS 4176.8 | 25m, 50m | 1.0m max |
| 20mm | Yellow (RAL 1033) | 500 kPa | AS 4176.8 | 25m, 50m | 1.25m max |
| 25mm | Yellow (RAL 1033) | 500 kPa | AS 4176.8 | 25m, 50m | 1.5m max |
| 32mm | Yellow (RAL 1033) | 500 kPa | AS 4176.8 | 25m, 50m | 2.0m max |
All pipe is clearly marked at 1m intervals with brand, type, size, class, standard, and licence number. Straight lengths of 5m are also available per size. Full technical specifications including bending radii, thermal expansion coefficient, and pipe sizing tables for natural gas and propane are detailed in the Elson EPS PEX Gas Installation Manual, available on individual product pages.
Key Features of EPS Gas PEX Pipe
- AS 4176.8 certified — tested and approved for gas installation under licence SMKP 21859, providing confidence in system compliance for licensed gas fitters
- Multi-layer PEX/AL/PEX construction — aluminium core bonded between two layers of crosslinked polyethylene, combining flexibility with gas barrier integrity and dimensional stability
- Yellow pipe for clear gas identification — colour coded RAL 1033 yellow for immediate on-site and future identification in accordance with gas installation standards
- Class 500 kPa pressure rating — rated across all sizes (16mm to 32mm) for typical residential and light commercial gas installations
- Leak before crimp design — by design, EPS PEX crimp joints will leak if not properly crimped, providing an immediate, visible indication of any uncrimped joint before the system is put into service
- Same tooling as EPS water system — the EPS crimp tool and jaws used for the water pipe range are also used for the gas pipe range, reducing tool investment for gas fitters already working with the EPS system
- 99.9% lead free fittings — EPS crimp fittings used with this pipe are manufactured from dezincification-resistant (DR) brass with less than 0.1% lead content
Installation Requirements
EPS Gas PEX pipe must be installed by a licensed gas fitter only, in accordance with AS/NZS 5601 and using EPS PEX Crimp Gas components under licence SMKP 21859. Key installation requirements include:
- Pipe preparation — every pipe end must be cut square and rounded and deburred using the EPS PEX Crimp Gas calibrating tool before insertion into the fitting. Full pipe insertion must be confirmed through the witness holes in the copper crimp ring before crimping.
- Crimp verification — every joint must be checked with the EPS crimp gauge after crimping to confirm the joint has been correctly compressed. A joint that fails the gauge check must be cut out and replaced.
- Protection and support — pipe must be protected from UV exposure, physical damage, excessive heat, and chemical or corrosive environments. Both vertical and horizontal clipping is required at the spacings specified per pipe size. Underground installations must comply with AS/NZS 5601, with no joints permitted beneath buildings or in-ground, and pipe embedded in concrete must be installed in-conduit.
- System identification — an identification tag must be permanently attached adjacent to the gas meter or LP gas cylinder on every installation, as required by AS/NZS 5601.
- System testing — all joints and fittings must be tested for leaks by the licensed installer prior to burying or concealing any part of the installation.
For full technical installation requirements, refer to the Elson EPS PEX Gas Installation Manual.
Frequently Asked Questions
What is EPS Gas PEX pipe made from?
EPS Gas PEX pipe is a multi-layer composite pipe with an inner and outer wall of crosslinked polyethylene (PE-Xb) bonded to an aluminium core — a PEX/AL/PEX structure. The aluminium layer provides a gas barrier and dimensional stability, while the PEX layers provide flexibility and corrosion resistance.
What standard is EPS Gas PEX pipe certified to?
The EPS Gas PEX/AL/PEX pipe is tested and approved in accordance with Australian Standard AS 4176.8 under licence number SMKP 21859. The complete EPS PEX crimp system is also manufactured and tested to comply with AS/NZS 2537.2, AS 2492, and AS/NZS 5601.
Who can install EPS Gas PEX pipe?
EPS Gas PEX pipe must only be installed by a licensed gas fitter, in accordance with AS/NZS 5601 and using EPS PEX Crimp Gas components. Installation by unlicensed persons is not permitted under Australian gas installation standards.
What sizes does EPS Gas PEX pipe come in?
EPS Gas PEX pipe is available in 16mm, 20mm, 25mm, and 32mm nominal sizes, in 25m and 50m coils. Straight lengths of 5m are available per size.
Can the same EPS crimp tool be used for water and gas pipe?
Yes. The EPS PEX manual crimping tools (Elson ALBA) and the Novopress ACO153 battery press tool with EPS-specific jaws are approved for use with both the EPS water and EPS gas pipe systems. The correct jaw size must match the pipe diameter, and every joint must be verified with the EPS crimp gauge.
Can EPS Gas PEX pipe be installed underground?
Underground installation is permitted in accordance with AS/NZS 5601, however no joints are permitted beneath buildings or in-ground. Pipe embedded in concrete must be installed in-conduit at a maximum pressure of 70 kPa. All underground fittings must be wrapped and protected.
