Saunier Duval 0020211088 Tube Expansion Vessel Heating

The Saunier Duval 0020211088 Tube is a genuine replacement connection pipe designed to link the heating expansion vessel to the boiler’s heating circuit. This tube allows excess pressure created during heating cycles to be safely absorbed by the expansion vessel, helping maintain stable system pressure and protect internal components.

A damaged, corroded, or leaking expansion vessel tube can cause pressure loss, water leaks, noisy operation, or boiler lockouts. Replacing it with this genuine Saunier Duval part restores correct pressure management and reliable boiler performance.
