Stop leaks and drips – Thanks to brass and ceramic sealing discs

Reliable sealing reduces slow drips and the need for repeated adjustments, conserving water and cutting annoyance from persistent leaks.
Straightforward replacement – With standard BSP 1/2" thread and 20-tooth spline
Cartridge uses a BSP 1/2" threaded connection and a 20-tooth spline, and is drilled and threaded to accept a 4mm fixing screw for secure mounting. The item is described as a universal size that fits many taps.
Most users can swap the worn cartridge for a like-for-like unit without changing tap hardware, saving time compared with replacing an entire tap.
Works on hot and cold supplies – With dual-suitable ceramic discs
Both ceramic discs are specified as suitable for hot and cold water, eliminating the need to match separate hot and cold parts. The quarter-turn action gives clear open/close positions.
One cartridge replaces either supply side in a mixer set-up, simplifying stockholding and ensuring consistent operation across both lines.
