Product Description
PEX-AL-PE pipes integrate the flexibility of plastic with the stability of metal. The aluminum layer provides excellent oxygen barrier performance, preventing microbial growth and corrosion in heating systems. The inner PEX layer ensures high-temperature resistance (up to 95°C), while the outer PE layer enhances durability.
