The Dornbracht 9090031620090 is a compatible spare progressive temperature-control cartridge for selected Dornbracht single lever mixer taps. Dornbracht documentation also shows the formatted code 90 90 03 162 00 90 and describes the part as a Lifetime progressive 180 degree temperature-control top.
This cartridge is used inside the mixer body to control progressive water flow and temperature through the tap handle. It can help resolve faults such as dripping from the spout when the tap is turned off, stiff handle movement, poor shut-off or inconsistent progressive temperature control where the existing cartridge is worn or scaled.
