PEX Pipe was invented in 1968. Pex pipe was used throughout Europe for water distribution systems. In mid 1980” Pex pipe was introduced in North America for the use of residential radiant floor heating systems.

By the mid-1990s, Pex pipe was being used for residential potable ( drinking )  plumbing. During the early 2000s, Pex Pipe was used for fire sprinklers for a “multipurpose” system.

Commercial projects began using PEX in the 1990s for radiant heating (and eventually radiant cooling) applications. Recently the use of Pex Pipe increase in using PEX pipe for domestic hot water, as well as hydronic heating and chilled-water applications.

Both residential and commercial industries see the same benefits of PEX Pipe, namely: 

  • Its flexibility and long coil lengths, dramatically reducing the need for fittings.
  • Its high durability, corrosion resistance and freeze resistance for greater longevity.
  • Its cost-effectiveness compared to materials like copper.

PEX is the acronym for Crosslinked Polyethylene.

Crosslinked Polyethylene is a polyethylene material which has undergone a change in molecular structure using a chemical or a physical process whereby the polymer chains are chemically linked. Crosslinking of polyethylene into PEX for pipes results in improved properties such as elevated temperature strength and performance, chemical resistance, and resistance to slow crack growth.

PEX pipe is static, meaning its properties remain constant over the course of its lifetime. It will never pit, scale, or corrode, eliminating the need to oversize. This also means that once PEX is designed and sized, it will continue to function in the same manner moving forward.

Optimizing a PEX pipe system can yield a number of cost-saving benefits, including smaller average pipe diameter, which translates to smaller valves, transition fittings, and hangers, less insulation, and lower labor costs.

The Pex Al Pex pipe G1 Distribution offers to the market in Southern Africa have their aluminum layer butt welded ensuring the pipe has a greater resistance to pressure and stresses generated when the pipes are installed.

hot water to reach the fixture.

Environmentally Sound – PEX is an inert material and does not contain volatile organic compounds (VOCs).

These Pex pipe fittings fit water and gas pipe for reticulation networks.

Pex Al Pex is quite easy to use and offers a great option for developments and the needs plumbers have with reticulation requirements.

G1 Gas now offers an outdoor PEX pipe that will have multiple uses from one pipe.

The pipe will be UV activated. This means it will have an outside UV protection layer.

The same pipe will have a high pressure operating rating according to Australian and New Zealand standards including EN. 10 Bar for hot water and 18 Bar for all other applications.

The same pipe will also be able to handle hot water up to 98 Degrees Celsius.

PEX pipe is a polymeric material formed by the chemical joining of individual polyethylene molecules in a process called crosslinking.

Crosslinking alters the performance of the original polyethylene polymer improving several key properties.

The primary reason for crosslinking polyethylene (PE) is to increase the material’s elevated temperature performance under load.

In addition, crosslinking substantially improves the pipe’s environmental stress crack resistance (ESCR), resistance to slow crack growth, chemical resistance, toughness and abrasion resistance.

PEX pipe is corrosion resistant (corrosion is not possible with PEX) to both soils and water.

No build-up of minerals inside the pipe which could reduce flow, high velocities are tolerated by PEX pipes without erosion corrosion.

PEX is a Green Solution:

Lower cost to the environment for production ; No mining operations for the ore ; Low energy cost to produce PE and PEX compared with copper ;  Smooth wall, excellent flow characteristics reduces pumping costs ; Proven long life and durability provides value ; Light weight of PEX reduces transportation costs ; Flexibility can dampen water hammer, reducing pressure spikes ; Protects health and safety ; PEX pipe does not add minerals to drinking water.

You as the installer will also be able to use this pipe for compressed air and air-conditioning piping.

Natural gas and LPG gas could be carried in this pipe as a high pressure solution as a first stage pipe.

PEX-AL-PEX is the first choice for a solar collector application.

PEX is a high-temperature flexible plastic pressure pipe. In the last 40 years it has been used extremely successfully in the European and global markets.

Pex Al Pex has gone through extensive testing for durability and material performance testing and time inspections and graduated with absolutely perfect scores.

The architectural design of PEX is so favorable that PEX pipe is listed for use in fire sprinkler systems as defined in NFPA standard 13D. This makes Pex pipe multiple times less expensive not only on product value but also in cutting down in labor costs saving loads of installation hours. 

Pex al Pex is easy to bend and can be used more easily in tight turns and one of the major advantages is that Pex al Pex pipe does not have any spring back.

Health and your way…


Vapor produced as the copper is melted during the soldering process is much more harmful. Its molecular size is smaller and lighter than dust. While dust clogs the pores and lungs, the vapor penetrates both, causing greater damage. Dust and vapors can cause conditions from dermatitis to cumulative lung damage.

Arsenic trioxide is a part of copper, and it is considered toxic. Skin lesions and nasal septum perforations along with dermatological troubles are just the start of troubles. It can affect the gastrointestinal and central nervous systems. It also increases the incidence of lung and lymphatic cancers over prolonged periods. Although arsenic trioxide is not technically copper, you ingest arsenic trioxide along with the copper.
