Replacement ceramic disc tap cartridges and Spout O Ring repair Kit to fit the Homebase Ontario Kitchen Mixer tap.

This is the 28 spline cartridge which fits in the later Ontario tap. (known by part 3602R) The cartridge was originally an 20 spline version. There is no way to identify from the tap itself which cartridge you need, you will need to count the teeth on the spline.

Original spare part codes for the cartridges 3602R and oring kit 1239.
