Mixet shower faucet cartridge made by Danco
 

The Mixet shower faucet cartridge 88200 made by Danco as MX-1 and sold
mainly by Home Depot may not fit your faucet due to the threads of its
bonnet assembly being different. You also may not be able to use your
old bonnet assembly with the new cartridge since it is slightly larger
than the bonnet opening.
