This is for Taps where you have a different valve ie. NOT SMR Valve in your own Tap and therefore might also need screws that fit the 3984R Valve as your Own original valve & screw might have had a different thread so your own screw will not fit this 3984R Valve. Please select the screws that we have advised, or if in doubt, purchase the length you think you require with a view to returning the ones unused.
The screws length are based on a dome shaped Philips Screw. Please check your own thread length and order accordingly.

- Genuine = Proper fit, tested by the Manufacturer
