Roca A525015803 Thermostatic Cartridge (Cartridge Only)

Summary

Roca A525015803 Thermostatic Cartridge (Cartridge Only)

This Roca A525015803 is a thermostatic cartridge for Roca RT12 thermostatic shower and bath-shower mixer assemblies. This Di Vapor listing is for the cartridge only and is intended to restore temperature regulation where the existing thermostatic cartridge is worn, scaled or no longer responding correctly.

The cartridge blends hot and cold water inside the valve body to control the outlet temperature. Common signs of a failing thermostatic cartridge include unstable shower temperature, the outlet running too hot or too cold, reduced temperature adjustment or the valve not responding properly at the temperature handle.

Technical Details

Before ordering, compare the part code, valve model reference and cartridge arrangement with the part being removed. Do not select this cartridge from size alone, as similar Roca thermostatic cartridges may use different locating details.
