What it is

The Mira 1.1663.166.1 Cartridge Assembly is a concentric thermostatic mixing cartridge manufactured by Mira. It forms the control element inside a compatible Mira shower valve, regulating the blend of hot and cold water to hold a steady outlet temperature.

Before you order

  • Confirm the part number 1.1663.166.1 matches the identification on the valve or the manufacturer's documentation.
  • Check whether the valve requires a concentric cartridge, as cartridge assemblies are supplied in different configurations.
  • Verify the valve model and any revision details before ordering, since cartridge fitment varies between Mira valve families.
  • Retain the old cartridge until the new assembly is fitted and the outlet temperature has been checked.
