Engineered for high-performance hydronic radiant heating, snow-melting systems, and demanding potable water networks, our Premium PEX-AL-PEX Composite Pipe delivers the ultimate combination of metal and plastic. This multi-layer tubing features an inner and outer layer of cross-linked polyethylene (PEX) permanently bonded to an interior aluminum core via a continuous longitudinal weld. This specialized construction provides a 100 percent oxygen barrier while combining the flexibility of plastic with the structural stability of metal.
The internal, welded aluminum core allows the pipe to hold its shape perfectly when hand-bent around obstacles, completely eliminating the spring-back effect found in standard PEX pipes. This saves installation time, minimizes the need for excess elbow fittings, and ensures a clean, professional looking mechanical layout.
Key Features and Benefit
Continuous Welded Aluminum Core: Features a precision-engineered overlap or butt-welded aluminum layer that provides rigid structural support, allowing the pipe to be shaped by hand and hold its form perfectly.
100 Percent Oxygen and Gas Barrier: The solid interior metal jacket completely prevents oxygen, gases, and contaminants from permeating the pipe walls. This stops corrosion on metallic components like boilers, pumps, and manifolds.
Low Thermal Expansion: The embedded aluminum core reduces thermal expansion and contraction down to a level similar to traditional copper pipe, preventing looping, sagging, and wall stress under extreme temperature swings.
High Temperature and Pressure Ratings: Designed to safely operate under rigorous commercial heating demands, handling working water temperatures up to 200 degrees Fahrenheit.
Smooth, Corrosion-Resistant Interior: The high-purity PEX inner lining resists scale buildup, pitting, and chlorine degradation, guaranteeing clean water delivery and low fluid friction over decades of use.
