If your kitchen tap is dripping or leaking out of the spout then it is time to replace / change the quarter turn ceramic disc cartridges.
Hot and cold valve replacements available. Cartridge has 20 teeth on spline.
You will require our Anticlockwise open cartridge for the cold side, and clockwise open for the hot side.
If you require both then you can select "Pair".

This cartridge may come out attached to an adaptor bush. The bush is a separate part.
There are different types of bush used on this cartridge so you will need to measure the thread on the bush.
This may be 28mm which is our SB28 (3409R SP3409 133.0069.390) or 34mm thread which is our SB34 (SP3408 3408R 133.0069.391) or 27mm thread which is SB27 (3868R SP3868 133.0312.538.)
You can try and separate your cartridge from the bush.
If you are struggling to remove your old bush it may be corroded on and you will need to purchase a new bush.
