This tap has been in production for over 2 decades.  While both valves (1212R and 3984R have the same measurements, the 1212R valve has a white seal and the later 3984R valve has a blue or red seal.  We would advise that you check your own valve before ordering i.e check the colour of the seal and the valve stamp. If your own valve is stamped San Marco / white seal , order the 1212R.  If your own valve is stamped SMR / blue or red seal, you can order the 3984R .  If you do not know which is in your own tap, then please buy the earlier 1212R white sealed valve.  This has a slightly larger seal than the later 3984R valve and we would recommend it for older tap models and it will guarantee, by ordering this 1212R white seal valve version, that irrespective of which version is in your own tap, you will be ordering a replacement valve that will work.  The later red / blue sealed 3984R version will not be as effective in older tap models.  If you order the red / blue sealed 3984R and your tap continues to drip and it transpires that you had the older 1212R White sealed valve version, then this would not come under warranty because you had not replaced your old valve with the correct valve per our recommendations.
