  • $975.00

Product 18.30.147, Model TX2

This world-class, high-flow thermostatic cartridge dynamically mixes hot and cold water to maintain the set water temperature. It also prevents very hot water to avoid scalding your skin.

Eurotherm invented the thermostatic cartridge in 1945. The Eurotherm brand of thermostatic valves have been in use worldwide for over 75 years.

This replacement thermostatic cartridge fits the Waterworks Opus 3/4" thermostatic valve GUSV45R.
