PEX-AL-PEX PIPE

The PEX-AL-PEX composite pipe has five layers, the inner and outer layers are PEX, which is tightly bonded to the middle layer of aluminum with melt glue, and the middle layer is longitudinally welded by butt welding or lap welding. This tube is the perfect combination of metal and plastic.

PEX PEX-EVOH PIPE

Flexible PEX heated red with smooth inner wall, good thermal stability and long-term pressure resistance, and no heavy metal additives, our PERT PEX pipe and fittings 15mm PEX pipe will not be covered with dirt or contaminated with bacteria.

PERT, PERT-EVOH PIPE

PERT pipe inherits the good flexibility, thermal conductivity and chemical inertness of PE material. At the same time, the design and synthesis of special molecules make them have higher heat resistance and pressure resistance under high temperature conditions. It is suitable for home heating and most housing applications.
