    Hi All

    I need to replace these 1960's rad valves and I'm not sure of the thread sizes.
    The 'vertical' thread is for a 22mm or 3/4in pipe connection but the 'horizontal' thread has a diameter of 31.5mm and the nut is 37mm across the flats.
    Are replacements for these valves available. I'm not too fussy about the style of the valve, old or modern but preferably chrome.

    Many thanks

    Or you could just buy two of 3/4" x 1/2" bushings and use 15mm radiator valves of your choice.
