The Vaillant 0020068956 Telescopic Connection Tube Kit is a genuine Vaillant replacement for ecoTEC Plus and ecoTEC Pro boilers. The copper tubes connect the boiler’s heat exchanger to its internal hydraulic assembly, carrying heating water safely between the two.
The telescopic design makes fitting easier, as the tube can be adjusted to the correct length during installation. Replace the tube if the old one is leaking, corroded or damaged, or if its seals have failed.
