Summary
Hudson Reed A3003CT Brass Thermostatic Shower Cartridge for Ultra A3003 Tec Pura Triple Shower Valve
The Hudson Reed A3003CT is a brass thermostatic shower cartridge for the A3003 Tec Pura triple thermostatic shower valve. This cartridge sits inside the thermostatic section of the valve and regulates the mixed water temperature by reacting to hot and cold supply changes.
Use this part when the existing A3003CT thermostatic cartridge is worn, seized, scaled or no longer maintaining a stable outlet temperature. Typical temperature-control faults can include fluctuating shower temperature, reduced control range or failure to achieve the selected mixed temperature.

Confirmed Valve Use
Before Ordering
- Match the removed cartridge to A3003CT and compare the cartridge body, brass construction, seals and spindle arrangement before ordering.
- Do not treat A3003PL, SA30049, SC50T20 or SC50T20-M as direct replacements for A3003CT unless the removed cartridge and valve documentation confirm that version is required.
- Cartridge seals should be lubricated with WRAS-approved silicone grease during fitting to help protect the O-rings and ease installation.
