Renowned as being the best jointing technology for gas and water applications since 1957, the extensive product range is used globally for transport lines, distribution lines, house connections and service lines. The components are used underground and aboveground, for new systems, extensions, service and repair work. Waga joined Georg Fischer in 1965, closing the gap between old and new pipe materials – cost-efficiently and safely at all times.
