Summary
Ideal Standard A952552N11 3/4 Inch Hot and Cold Ceramic Disc Cartridge Pair for Dualux, Monolux and Domi Duo Bath Fillers
The Ideal Standard A952552N11 is listed as a hot and cold pair of 3/4-inch M33 DX ceramic disc flow cartridges for selected Ideal Standard Dualux, Monolux and older Domi Duo bath fillers. These screw-in cartridges control the on/off water supply through the separate tap handles.
The ceramic disc mechanism allows water to flow when the tap is opened and shuts off the supply when the handle is closed. Worn or damaged cartridges can cause water to drip from the bath spout when the taps are turned off, difficulty operating the handles or incomplete water shut-off. Fitting the correct cartridges can help restore reliable operation without replacing the complete bath filler.

Before Ordering
Check the existing cartridges and confirm the bath filler model before ordering. The production date is particularly important for Domi Duo fittings, as later versions can use a different cartridge arrangement. Compare the screw thread diameter, shoulder diameter, handle spline, cartridge body height and operating directions with the removed cartridges. The 3/4-inch nominal size alone is not sufficient to identify the correct parts.
Isolate the hot and cold water supplies before removing the existing cartridges. Check that the cartridge seating surfaces are clean and that the seals are correctly positioned. Apply a small amount of suitable silicone grease to the O-rings and seals where required during installation.
