Product Description

The PEX-AL-PEX pipe is a high-performance composite pipe consisting of five layers. An aluminum layer is pressed between inner and outer layers of PEX (silane crosslinking polyethylene), combining the superior strength of metal with the exceptional durability of plastic.

It can withstand working temperatures up to 95°C and a pressure of 1.25MPa, making it ideal for high-temperature radiation heating and demanding water distribution systems.
