The Sime 5139130 is an expansion vessel intended for use within Sime gas boiler installations. It carries the manufacturer designation "1.8" and terminates in a 3/8" male connection. The vessel accommodates the change in system water volume as the boiler heats and cools, helping to stabilise pressure within the heating circuit.
