Rangemaster TRS1 Tap Valve Hot or Cold

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.

Here is our own valve measurements.

Valve Measurements
Overall height: 50mm
Nut Height: 8mm
Diameter at thread: 21mm
Splines: 20
Height of Splines: 8mm
