What it is
The Worcester Bosch 87161064300 is an expansion vessel connector — an adaptor that links the expansion vessel to the hydraulic circuit of the appliance. It is a Worcester Bosch component intended for the Greenstar i System boiler family. Its job is to provide a sound, sealed connection at the vessel so the system can absorb the change in water volume as it heats and cools.
