Thanks for getting in touch with Tundra Restaurant Supply with your question Tony.
This T&S Brass 002714-40 Eterna Hot Cartridge Stem Assembly can be used with your mop sink, but the manufacturer does not recommend it due to the cartridge not having a spring check inside.
That said, we do carry the appropriate replacement cartridges for your sink. I've included both the hot and cold handles below for your convenience.
