New: alpex-duo XS fitting with all-plastic thread
The alpex-duo XS family keeps on growing: A new adapter with a male thread made entirely of plastic complements FRÄNKISCHE’s installation system for drinking water and heating. The all-plastic design offers the same applications as the proven brass components and is additionally suited for special applications, for instance, with corrosive water.
The flow-optimised alpex-duo XS multilayer composite pipe system in dimensions 16 to 32 mm is simple, reliable, and, above all, future-oriented – flexible in any installation situation and practice-oriented thanks to convenient and time-saving assembly. A press fitting with a male thread made of the high-performance plastic PPSU (polyphenylsulphone) is the new addition to the range: “With the new threaded adapter, we are specifically expanding our range of PPSU components, which we manufacture with great know-how based on decades of experience. For our customers, this means sustainability and price stability”, says Willi Mattolat, Product Manager in FRÄNKISCHE's Building Technology Division.
Fitting with plastic thread for corrosive water
In addition, the adapter with the all-plastic thread, according to DIN EN 10226-1, expands the applications of alpex-duo XS: besides tried-and-tested drinking water and heating installation, it also allows special applications. Since the new pipe connector excludes corrosion, it can also be used in special cases, such as with corrosive water. Additional fields of application are, for example, rainwater or well water that does not comply with the regulations of the German Drinking Water Ordinance (TrinkwV), is not regularly monitored and where corrosion could occur.
Easy processing without calibration
You process the new press fitting the same way as the existing alpex-duo XS threaded brass fittings: Push the fitting onto the pipe – no calibration required – and press using an F or TH contour. To seal the thread, craftsmen use standard sealants such as hemp or sealing cord. Large inspection holes in the fixing ring facilitate inspection during installation, and the leakage function makes installation even safer.
The new alpex-duo XS adapter is available in five versions: in dimension 16x2 with R3/8, R1/2 and R3/4 threads, as well as in dimension 20x2 with R1/2 and R3/4 threads. The alpex-duo XS installation system is compatible with FRÄNKISCHE pipes and fittings from the alpex L product range for large dimensions from 40 to 75 mm and with the alpex-plus push-fit fitting in dimensions from 16 to 26 mm.
