Grohe 28mm SilkMove Ceramic Cartridge — 46963000
The Grohe 46963000 is an authentic, factory-original 28mm ceramic disc cartridge engineered specifically for Grohe single-lever basin mixers, bidet taps, bath/shower valves, and kitchen sink taps. Equipped with Grohe's proprietary SilkMove ceramic alloy discs and coated with advanced lubricants, it ensures ultra-smooth handle operation and precise flow and temperature control. If your tap is constantly dripping from the spout, leaking from around the handle lever base, or has become stiff or difficult to operate, this genuine drop-in replacement restores full factory performance and a watertight seal.

Installation Note
Always isolate both hot and cold water supplies before starting. Remove the indice cap on the lever, loosen the retaining grub screw (typically 3mm hex), remove the handle, and unscrew the decorative cap and brass retaining collar. When inserting the new 46963000 cartridge, ensure the two locating alignment pins on the base slot securely into the corresponding holes inside the tap body before tightening the retaining nut. Do not overtighten the retaining collar, as excessive torque compresses the ceramic discs and makes handle operation stiff.
