PEX Systems
Four engineered systems for domestic and commercial water and gas installations.
Yellow/Green Water & Gas Crimp System
PEX-B PE100 PN16/PN20 is a WATER & PEX-AL-PEX GAS CRIMP JOINT SYSTEM. The Lightning PEX-b PE100 PN16 and PN20 system is a competitively priced option for installers and efficient to install. The PEX-b PE100 system is designed to be cost effective in domestic and light commercial installations.
Pipe Benefits
- —Corrosion resistance
- —Acoustic insulation — minimal noise caused by water transfer
- —PEX pipe flexibility reducing water hammer
- —No build-up of lime or scale in the bore of the pipe
- —Strong material with superior performance against abrasion and impact

- ✓Black PE outer layer
- ✓Dimensions 16–25mm
- ✓Blue Crimp / Sleeve / Lightning only
Sleeve Gas Pipe (PEX-AL-PEX)
Form-stable aluminium core; install to AS/NZS 5601.1:2013; normal 80°C; up to 70 kPa @ 80°C.
- ✓Five layers with aluminium core (oxygen diffusion barrier)
- ✓Yellow PEX outer layer
- ✓Suitable for NG and LPG
- ✓Dimensions 16–32mm
- ✓Rigid, holds shape when installed
Lightning Expansion System
Lightning PEX-a pipe with lead-free brass or Stainless-Steel fittings, engineered to be fast and reliable. With only one tool, the system is up to 30% quicker than PN20 compression joints. Using the thermo-elastic memory of PEX-a, the pipe and ring apply increasing pressure on the fitting to deliver a strong seal for cold and hot water.
