National Shower Spares

Mira 903.33 Excel thermostatic cartridge assembly. Also known as a Mira Select MK1 thermostatic cartridge assembly. Suitable for high and low pressure installations. This 903.33 model replaces the earlier versions of 903.27 (low pressure, yellow hub) and 903.28 (high pressure, green hub), which are both now discontinued. *** Please note the body colour of the cartridge is now beige, not black as per some of the photos, due to a design change in early 2019. *** *** Please note that the adjustment key is no longer included included, as of December 2023, and was discontinued as a part in February 2026. A large flat-head screwdriver can be used as an alternative when making adjustments. *** This product is for shower models made prior to 2003. For Mira Excel models after 2003, please see the Mira 451.71 thermostatic cartridge assembly instead. Genuine brand new Mira product, covered by a Mira manufacturer's guarantee.
