How do I know if this cartridge fits my kitchen tap?

Please count the number of teeth on the spline (the top part that fits into the handle). Our cartridge is designed to be a compatible replacement for various premium kitchen taps that require this specific 28-teeth configuration.

Is this compatible with high-end European brand taps like the Ascona series?

This valve is specifically engineered to be compatible with 28-teeth spline models often found in high-end kitchen tap series. We recommend checking your original part's dimensions and tooth count to ensure a great fit before ordering.

What is the material of this replacement valve?

Our cartridges are made of high-quality solid brass and ceramic, ensuring durability and a leak-free experience. The 28-teeth design provides a precise and secure connection for your tap handle.

Does it come with the necessary screws for installation?

Yes, each 28-teeth cartridge comes with a matching M4 screw to ensure you have everything needed for a quick and easy replacement process.

What should I do if the handle is still loose after installation?

A loose handle usually means the tooth count doesn't match. Please double-check that your tap requires a 28-teeth spline. If you have the correct 28-teeth handle, our precision-machined spline will provide a tight, wobble-free fit.
