46mm Ceramic-Core Replacement

With a precise 46mm diameter and approximate weight of 85g, this cartridge replacement pairs a ceramic disc core — engineered for low-friction, high-cycle durability — with a robust ABS outer shell. It is designed exclusively for single-handle mixing valves used in UK domestic sink faucets, particularly Grohe 46048000 models. The ceramic disc enables smooth, quiet, and accurate temperature modulation, resisting abrasion and chemical erosion from everyday water exposure. The ABS housing adds mechanical resilience and maintains dimensional accuracy under standard UK water pressure (up to 5 bar), contributing to dependable leak-free operation. Installation requires original fasteners and careful preparation: internal valve components must be cleaned and inspected to ensure debris-free seating. The included 5 cm screws are specific to this application and should not be substituted across different faucet families.
