About This Product
Is your shower temperature all over the place – freezing one second, scalding the next?

That's probably a worn-out thermostatic cartridge.

This brass replacement spool is designed to fix that.

It's a G1/2-inch (DN15) valve that mixes hot and cold water to keep your shower at a consistent temperature.
It takes cold water between 5-29°C and hot water from 50-95°C, and it outputs mixed water in the 35-45°C range with an accuracy of about ±2°C.
Working pressure range is 0.
03 to 1.
0 Mpa, with 0.
1-0.
5 Mpa recommended for best results.
Flow rate is about 11.

67 liters per minute at 1 bar pressure, which is plenty for a decent shower.
Built from solid brass, so it's corrosion-resistant and durable.

Comes with a 5-year warranty against manufacturing defects, and it meets or exceeds industry standards.

Straight swap for most standard thermostatic shower mixers – gets your water temp back under control.
