Hudson Reed A3290 Thermostatic Cartridge for Tec Sequential Concealed and Exposed Shower Valves (ULTRA)
The HUD-A3290-CT thermostatic shower cartridge is used in Hudson Reed A3290 Tec sequential shower valves, including concealed and exposed installations.
The cartridge regulates the mixed water temperature within the valve. The Tec sequential control turns the water on and adjusts the temperature through one handle, starting with cold water and gradually blending in hot water as the control is turned anti-clockwise.

Before Ordering
Compare the removed cartridge, spindle adaptor and handle fitting with the product photographs. Some Tec sequential arrangements require a separate spindle adaptor, so keep the original parts for comparison and check the installed control arrangement before ordering a cartridge or handle.
Fitting and Temperature Checks
Isolate the hot and cold water supplies before removing the old cartridge. Apply a small amount of suitable silicone grease to the cartridge O-rings during installation, then check for leaks and confirm the shower temperature before use. If the shower remains too hot, too cold or unstable, check the supply temperature and pressure as well as the cartridge and control adjustment.
