Viega Pexfit Pro Fosta Pipe System are as flexible as you wish and as durable as you expect them to be.

Viega, founded in Attendorn, Germany in 1899, is one of the leading manufacturers of installation technology for sanitary and heating. Their range consists of approximately 17,000 articles in the product categories of piping systems as well as pre-wall and drainage technology.
The company has now introduced a new pipeline system – Pexfit Pro Fosta – for drinking water and heating systems. It is one of the innovative installation product under composite pipe system that are as flexible as you wish and as durable as you expect them to be. Made of physically cross-linked polyethylene (PE-Xc), these pipes are temperature and pressure-resistant compared to CPVC pipes, insensitive to corrosion and incrustation.
A Pexfit Pro Fosta series variant has three layers – PE-Xc internal pipe, an aluminium layer and white external coating – thereby making the pipe form stable i.e., once bent into close radii, the pipe permanently retains this shape eliminating the need for elbow joints.

Viega’s Pexfit Pro system comes with the advantage of Viega’s press connection technology to ensure leakage-proof joints. Once crimped using the Viega press tool (tool calibration and bevelling are not required), these joints become permanently leak-proof.

Whether made of polyphenylsulfone (PPSU) or red brass, Viega´s press connectors feature the SC-Contur. SC-Contur makes unintentionally un-pressed joints easily visible during a leakage test or when the system is filled.
A complete installation can be inspected centrally on the manometer as long as the components are all fitted with the SC-Contur. Only threaded connectors must be inspected individually in advance; central inspection is a huge advantage for those executing large projects.

The Pexfit Pro Fosta pipes are available in 16 to 63 mm. An extensive range of Pexfit Pro connectors with press connections also allow quick and uncomplicated crossover to metal pipe systems.
