Colour-Coded EPS PE-Xb Pipe for Every Water Application

EPS Water PEX pipe is a crosslinked polyethylene (PE-Xb) piping system manufactured by Elson, designed for residential and commercial water installations across Australia. The pipe is flexible, durable, and joined using the EPS crimp fitting system — making it a reliable trade choice for new builds, renovations, and system upgrades.

One of the key advantages of the EPS PE-Xb system is its colour-coded pipe range. Each application has a designated pipe colour, keeping installations compliant, clearly identifiable, and easy to inspect. Browse the full water pipe range online and order 24/7 with fast Australia-wide delivery.

EPS Water PEX Pipe Range

In-conduit options are available for 16mm and 20mm black cold water pipe, with the pipe pre-sleeved in a protective conduit for installations requiring additional protection or concealed routing through slabs and cavities.

Choosing the Right EPS Water PEX Pipe

Cold water (black) is the most commonly specified EPS pipe variant, available across the full size range from 16mm to 32mm. The 100m coil options in 16mm and 20mm offer better value per metre on larger jobs. The 25mm and 32mm sizes suit mains connections and sub-mains where higher flow capacity is required.

Hot water (red) pipe is available in 16mm and 20mm — the sizes most commonly used for domestic hot water distribution from storage systems or continuous flow units to fixtures. EPS PE-Xb pipe is rated for hot water service and maintains its structural integrity at typical system temperatures.

Rainwater (green) pipe keeps rainwater supply lines clearly identifiable and separate from potable water systems, as required under AS/NZS plumbing standards. Available in 16mm and 20mm for typical domestic and light commercial rainwater reticulation.

Recycled water (lilac) pipe meets the colour coding requirements for Class A and Class B recycled water distribution systems. Available in 16mm and 20mm, it's suited to installations in properties connected to recycled water supply for toilet flushing, irrigation, and similar non-potable uses.

In-conduit pipe is suited to installations where the pipe is run through a concrete slab, behind render, or in locations where post-installation access or replacement may be required. The conduit sleeve protects the pipe and allows for future extraction without structural work.

Key Features of EPS PE-Xb Water Pipe

• Crosslinked polyethylene construction — PE-Xb pipe has a molecular structure that gives it superior temperature and pressure resistance compared to standard polyethylene, maintaining performance across hot and cold water service conditions
• Flexible and lightweight — easier to handle and route than rigid pipe, particularly useful in tight spaces and long runs
• Colour-coded for compliance — each pipe colour meets AS/NZS identification requirements for its application, simplifying inspections and future maintenance
• Crimp jointing system — joined with EPS brass crimp fittings and a dedicated crimping tool for consistent, verifiable connections
• Available in trade coil lengths — 25m, 50m, and 100m coils to suit jobs of all sizes

Frequently Asked Questions

What is EPS Water PEX pipe used for?
EPS Water PEX pipe is used for hot and cold water supply, rainwater reticulation, and recycled water distribution in residential and commercial plumbing installations. The pipe is colour-coded by application and joined using the EPS crimp fitting system.

What does PE-Xb mean?
PE-Xb refers to the method of crosslinking used in the pipe's manufacture — peroxide crosslinking (the "b" designation). Crosslinking creates bonds between the polyethylene polymer chains, improving the pipe's temperature resistance, pressure rating, and long-term durability compared to standard polyethylene pipe.

What sizes does EPS Water PEX pipe come in?
Cold water black pipe is available in 16mm, 20mm, 25mm, and 32mm. Hot water, rainwater, and recycled water variants are available in 16mm and 20mm. Coil lengths range from 25m to 100m depending on the pipe size and type.

Can EPS PEX pipe be used for hot water?
Yes. The red EPS PE-Xb pipe is rated for hot water service and is available in 16mm and 20mm. PE-Xb crosslinked polyethylene maintains its structural integrity at typical domestic hot water system temperatures.

What fittings are used with EPS Water PEX pipe?
EPS Water PEX pipe is joined using EPS brass crimp fittings — including couplings, elbows, tees, BSP connectors, breeches, and adaptors — installed with either the Elson ALBA manual crimping tool or the Novopress ACO153 12V battery press tool. See our full EPS PEX pipe and fittings range for the complete fittings suite.

What is in-conduit EPS PEX pipe?
In-conduit EPS PEX pipe has the PE-Xb pipe pre-sleeved inside a protective conduit. This is used where the pipe is run through concrete slabs, behind render, or in locations where the pipe needs protection or future replaceability without structural access.
