⚡ At a Glance
- • Sealing Performance: High-hardness ceramic disc paired with a brass body, engineered to stop leaks and hold a watertight seal.
- • Best for: DIY homeowners and plumbers replacing quarter-turn kitchen and basin taps, including Franke Olympus SP3561.
- • Not ideal for: Taps that do not use a BSP 1/2" thread or have a different spline count than 28.
A 53mm-high replacement cartridge with a 20.5mm thread width and 28 splines. Built for compatibility with BSP 1/2" double-handle kitchen and basin taps and designed for long service life.
Stop Persistent Leaks – with a 28-spline ceramic disc
A precision ceramic disc works against a matching seat inside the cartridge, creating a watertight seal when closed. The brass backing adds rigidity so the ceramic stays aligned under repeated use.
Reliable drip elimination for taps that currently leak, saving the need for a full tap replacement. Expect fewer call-outs and immediate reduction in wasted water.
Longevity Under Regular Use – thanks to high-grade ceramic and brass construction
Materials are specified to withstand heavy use, with a rated life cycle of around 500,000 quarter-turns. Ceramic hardness resists wear while the brass body prevents distortion from plumbing stresses.
Parts last far longer than cheaper washers or worn cartridges, meaning fewer repairs over time and a lower chance of recurrence.
Quick, Straightforward Replacement – with BSP 1/2" thread and M4 fixing
Threaded shaft matches standard BSP 1/2" tap fittings and the cartridge is drilled and threaded for an M4 screw for secure mounting. Dimensions, including 53mm height and 20.5mm thread width, match common spare-part specifications.
Swapping the cartridge is a practical weekend DIY job for most homeowners, avoiding the cost and hassle of replacing the entire tap assembly.
