Benefits

Fully bonded polyethylene / aluminium construction combines the advantages of both metal and plastic tubing. The tubing is manufactured in long continuous lengths that can eliminate many fitting connections, yet it is light enough for an installer to carry to practicallt any location. It has a shape holding ability 'stay put' characteristics which can provide neat looking bends without special bending tools, yet the metal reinforced tube wall gives greater pressure ratings than plain plastic tubing. The tube can be cut cleanly with a standard utility knife.

Greater Strength

The outer high-density polyethylene layer is impervious to most chemical containing atmospheres and enables the tube to out perform practically all types of unprotected metal tubing. It is corrosion, water and steam resistant; it is very slightly permeable. The majority of thermoplastics, though having weak water absorption, are steam and gas permeable. The inner aluminium sheet reduces this phenomenon to the bare minimum.

Easy to Install

The inner aluminium layer adds tube wall strength that permits the tube to span large distances without additional support. It also makes a perfect tubing choice for direct burial without additional protection from concrete to earth installations. Welding projections do not damage the tubing or its performance level.

Connection

Tubes are sized to connect with standard compression fittings without special tube preparation. Full plastic tubing implies the use of connections including plastic supports and ends. Sheathed metal tubes must usually be stripped before being connected however this tube eliminates this operation.
