Brass expansion vessel, a replacement part for the hydraulic circuit of espresso machines. It absorbs the increase in water volume as it heats inside a closed circuit, preventing the pressure spikes that make the group drip and the expansion valve lift. Fits La Cimbali machines.
As water heats inside a closed circuit it expands and pressure rises. The expansion vessel takes up that surplus and damps the rise, protecting the gaskets, the pump and the valves in the circuit.
Does it fit La Cimbali machines?
Yes, it is intended for the circuit of La Cimbali machines. Before ordering, confirm the machine model and the connections of the vessel fitted, as generations differ in threads and positioning.
What is it made of?
It is made of brass, the usual choice in the hydraulic circuit for its pressure and corrosion resistance. It is supplied as a part compatible with the machine listed, with no agency relationship with the equipment brand.
What symptoms point to a spent vessel?
Dripping from the group between shots, the expansion valve discharging often, and the gauge climbing above normal at start-up. All are signs the circuit has nowhere left to absorb thermal expansion.
