Rangemaster TRS1 Tap Valve
This is a very old discontinued tap and the valves used in it back then are no longer available. We have a version of that old valve, the 1212R with white seal, and have fitted this valve with mixed success.
Please check your own valve, even if 20 splines, to the details here (especially the nut height as if your own nut height is lower than 8mm, it is possible that the current 1212R valve would cause a gap between the handle and the black detail on your tap). If not sure, then email us your own measurements plus picture of your own valve and whatever markings are on your own valve to sales@tapsandsinksonline.co.uk.
