PEX-AL-PEX Pipe: 5-Layer Protection, Lifetime Performance
Product features
PEX-aluminum composite pipe features an ultra-wide temperature resistance range:long-term operating temperature from -40℃ to 95℃, with short-term temperature resistance up to 110℃.
The middle aluminum layer significantly improves pressure resistance, ensuring system safety. It provides a complete oxygen barrier to protect metal components in the system.The aluminum layer also restricts thermal expansion and contraction, maintaining excellent dimensional stability.
The inner and outer PEX layers are non-toxic, odorless, bacteria‑resistant, and can withstand corrosion from chemicals and microorganisms in water.
