This cup lid seal fits the Wagner Finecoat Maxum II HVLP Spray gun cup (cup p/no. 0277183).
It is particularly important that lid gaskets on HVLP turbine guns are regularly inspected and changed, if necessary. This is because unlike suction feed airspray guns, the cup is positively pressurised. If the pressure is not maintained paint will not flow to the spray gun nozzle.
