The Auspex Gas System is a multi-layer pipe made from Cross Linked Polyethylene (PEX) on both layers and aluminium in between. Having PEX on both layers ensures that the highest performing polymer is on both sides of the aluminium core.
The Auspex Gas Manual covers the Auspex Gas Pipe system, a multi-layer pipe with cross-linked polyethylene (PEX) inner and outer layers and an aluminium middle layer. It describes the pipe and fitting system for professional plumbers and gasfitters, including sizes from 16 mm to 32 mm, copper crimp rings on 16–25 mm fittings and stainless steel crimp rings on 32 mm fittings.
The manual includes a data sheet, bending guidance, support spacing, thermal expansion calculations, fire and heat clearances, chemical and UV resistance, silicone burial wrap instructions and jointing steps for 16 mm to 25 mm fittings. It states that installations should comply with AS/NZS 5601 and that the installer must be a licensed gasfitter.
