DANCO Single-Function Pressure-Balance Temperature Control Hot and Cold Water Cartridge for Delta Momitor, White, RP46074, 1-Set (10664) This was built for use with Delta MultiChoice Universal valve body and fits Delta OEM #RP46074 (13/14 Series), which is all similar to Danco Model #10347, but can become confusing since Delta makes two very similar stems. Was made to work with hot and cold single-handle tub/shower faucets and was designed to provide single-function pressure-balance temperature control which keeps water temperature within a safe range. Made of a plastic construction for durability and makes an easy alternative to replacing you entire faucet which can save water, time and money. This product is in compliance with the Reduction of Lead in Drinking Water Act. Finished in gray and white to build-up a sleek and stylish look.
