This insulated 3/8 + 5/8 inch aluminium duct is suitable for professional applications in air conditioning, refrigeration, and climate control. The duct is supplied on a 30-meter roll and combines two aluminium pipes with different diameters. This makes this version practical for installations where a combination of pipe sizes is required.

The aluminium pipes are made of high-quality and flexible aluminium, making them easy to work with during installation. The 3/8 inch pipe has an outer diameter of 9.52 mm and a wall thickness of 1.0 mm. The 5/8 inch pipe has an outer diameter of 15.88 mm and a wall thickness of 1.3 mm. The constant wall thickness ensures reliable and uniform execution over the entire length.

Both pipes are equipped with high-quality PE insulation. The 3/8 inch pipe has an insulation thickness of 9 mm and the 5/8 inch pipe has an insulation thickness of 10 mm. The insulation consists of two resilient layers and is finished with a hard, white outer wall. The inner layer is heat-resistant up to 120 °C and offers additional protection during use and installation.

Thanks to the closed cell structure of the inner and outer walls, the insulation possesses good insulating properties. With a thermal conductivity of up to 0.043 W/mK, the insulation helps limit heat transfer. Additionally, the design is engineered to prevent condensation, which is important for applications within refrigeration and air conditioning systems.

The flexible construction makes the pipe practical during installation. When bent, the insulation is designed not to wrinkle easily, allowing the pipe run to be followed neatly. The protective caps are red and yellow, so that the different pipe diameters are easy to distinguish during assembly.

The cable complies with EN 13501-1 and has fire class BL-s1-d0. The 30-meter roll is supplied in a separate box, ensuring storage and transport remain organized. This combination of aluminium pipes, PE insulation, good thermal properties, and practical handling makes this cable suitable for a wide range of professional installation projects.
