*KeyFeatures *PREMIUM MATERIAL- PEX AL PEX Tubing Pipe inner and outer layers of aluminum-plastic pipe are cross-linked polyethylene materials, with a thick aluminum layer in the middle, laser fusion, three-layer protection, environmental protection, non-toxic, durable *HOT & COLD WATER PIPING- PEX-Al-PEX tubing has a small thermal expansion coefficient (expansion coefficient: 0.025 mm / mC), high- pressure resistance, corrosion resistance, and excellent performance. 1/2' PEX AL PEX tubing can be used for the transportation of cold and hot water fluids (Working Temperature: -40 ~ 95 ) *FREELY BENDABLE- Radiant floor tubing PEX AL PEX middle aluminum material increases the toughness of the pipe, which can be bent freely without rebound, easy to cut, process, and easy to install and construct *SUPERIOR CONVEYING- The inner wall of the white PEX-Al-PEX pipe is smooth, and the resistance is small when conveying fluid, and its ability to convey fluid is 30% larger than that of metal pipe with the same diameter *WIDE APPLICATION- PEX-Al-PEX pipe has the advantages of both plastic and metal and has become the preferred pipe in the cold, hot water, heating, and gas pipeline construction fields ******************************************************************************************************* *Specifications Total Length: 300m (Approx. 984') Overall Thickness: 2mm (Approx. 0.08") PEX Thickness: 1.7mm (Approx. 0.067") Aluminum Thickness: 0.21mm (Approx. 0.008") Interior Diameter: 12mm (Approx. 0.5") Exterior Diameter: 16mm (Approx. 0.6") Pressure Range: 6~8Mpa Working Temperature: -40~95 (-40~203) Continuous Working Temperature:
