The Wavin Tigris tube consists of a core of Aluminum with a plastic layer on both sides. Due to the insulating plastic layers, Wavin Tigris cannot be used as a grounding conductor. The tube can be easily bent by hand, for short bends a bending spring or pliers must be used. The tube remains dimensionally stable and does not spring back after bending.
Best innovation in my opinion in plumbing technology. Easy to use with new push fittings. No need to mess with brazing and torch. Just cut to size and push to fit. Anti-copper theft too.
