What it is
A set of sealing washers manufactured by Worcester Bosch for use in its domestic boiler range. The washers sit at joints and connections where a watertight seal is needed, compressing under load to stop water tracking past a fitting. This set is listed against the Greenstar family and other Worcester Bosch appliances, including the R35 HE Plus Combi.
Signs this part needs replacing
