Item Description


The Advantage of Plastic and Metal Combined

PEX-AL-PEX tubing represents a groundbreaking fusion of plastic and metal engineering, combining the corrosion-resistant properties of PEX plastic with the structural advantages of a metal pipe. Classified as Grade B and featuring an overlapped design, this tubing stands out for its innovative construction. Grade B PEX is chosen for Duda Energy PEX-AL-PEX for its remarkable strength which provides a higher burst pressure than typical Grade A PEX.

Crafted with a PEX inner and outer layer, the tubing is reinforced with a strategically placed aluminium core, forming a durable and flexible composite structure. The aluminium not only enhances the tubing's rigidity, making it effortlessly bendable and keeping it in the desired shape without the need for additional elbows, but it also serves as a highly effective oxygen barrier. This prevents corrosion of adjacent metal components, ensuring long-lasting performance.

PEX-AL-PEX tubing outshines regular PEX tubing in numerous aspects. The added rigidity from the aluminium core simplifies installation, making it easy to shape and preventing the tubing from resembling a tangled mess. The tactile feedback during bending helps prevent over-bending, ensuring precise configurations without the risk of kinking.

The tubing boasts low roughness and true inside diameters, resulting in optimal fluid flow with minimal pressure loss. With a low coefficient of hydraulic resistance, it excels in efficiency and performance. Ideal for radiant floor heating applications, PEX-AL-PEX tubing exhibits an extended service life, providing a reliable solution for both residential and commercial settings.

Premium Construction: This PEX-AL-PEX tubing boasts a length of 100 or 50 meters (160/320 feet) and features a robust structure with 2 to 3mm total thickness. The PEX layer is 2.7mm thick, ensuring durability and longevity.

Top-Grade Material: Crafted from the highest quality Grade B PEX-AL-PEX, this tubing is equipped with a 0.3mm aluminium layer for enhanced strength. The oxygen barrier is a crucial component, making it ideal for use in radiant floors, glycol loops, and floor heating/furnaces.

Wide Temperature Range: With a remarkable working temperature range from -40?C to 95?C, this tubing is suitable for various applications. Its reliable performance ensures efficient operation even in extreme conditions.

High Pressure Resistance: Designed to withstand high pressures, the tubing has a working pressure of 2.5 MPa (362 psi) and a maximum bursting pressure of 5.0 MPa (724 psi). This exceptional pressure tolerance ensures reliable and safe performance in demanding applications.

Certified Quality and Longevity: ISO9001 certified, this PEX-AL-PEX tubing guarantees quality and adherence to industry standards. Boasting a service life expectancy of 50 years, it is a reliable choice for domestic water supply, glycol loops, and any application where longevity and performance are paramount. Safe for use with potable water, it provides peace of mind for various plumbing needs.
