46mm Single-Handle Cartridge

This 46mm-diameter cartridge replacement weighs approx. 85g and integrates a wear-resistant ceramic disc core inside a durable ABS housing. It is intended for single-handle mixing valves in residential UK sink applications. The ceramic disc ensures precise rotational control with negligible friction, preserving tactile feedback and responsiveness over extended use. The ABS enclosure offers impact resistance and dimensional consistency, remaining stable under continuous exposure to water pressure up to 5 bar — typical of UK mains-fed systems. Compatibility is limited to Grohe 46048000 and other 46mm-standard single-handle sink faucets. Installation depends on retaining original mounting hardware (screws, washers, spacers); the provided 5 cm screws are model-specific and not cross-compatible. Before fitting, remove old cartridge residue and flush valve cavity to eliminate grit or scale that could impair sealing or disc motion.
