More informationConnection of high flow heating and air conditioning devices. External diameter 44mm, nominal flow 650l./min, radius of curvature 70mm, sanitary service pressure 16 bar / + 70ºC, heating temperature 12 bar / + 90ºC. Composed of corrugated HDPE pipe covered by an AISI 304 stainless steel braid, the EXTRA TWIST range of connections is extremely flexible and does not collapse. The hoses offer an optimal flow without restriction. They are designed for the connection of heaters, softeners, pumps, meter batteries, heating systems and water filtration. Thanks to its very small radius of curvature, this flexible corrugated does not collapse and fits in tight spaces, it has excellent resistance to acids, alkalis, salts and solvents. An antibacterial HDPE pipe guarantees compliance with the European Water Directive (DWD) regarding metals. The EXTRA TWIST range incorporates metallic elements that comply with the European Water Directive (DWD), which defines the limits of accepted impurities in metals in contact with water. It guarantees that the quality of drinking water at the tap outlet is adequate.
