Frequently Asked Questions
How do I know which UC size I need?
Use the Finder Tool variant — it's a precision metal plate that identifies your tap's spline count so you can select the correct UC number.
What's the difference between these and the TC ceramic cartridges?
These are standard (multi-turn) valve cartridges. If your tap has a quarter-turn mechanism, you'll need the TC ceramic disc cartridges instead.
Are these sold as a pair?
Yes — the UC variants are sold as matched hot and cold pairs.
What taps are these compatible with?
They fit most standard UK basin, bath and kitchen taps with a 1/2" BSP thread and a traditional multi-turn valve mechanism.
