replacing leaking1 1/4 brass angle steam radiator valve

DougP Member Posts: 13
now realize that the old crane valve is about 3/8 higher than newer models, my replacement is a Blue Fin , but have looked at other brands Hammond, Red White and others seem to all be shorter in length from the bottom of the valve to mid angled opening. Tried to make it work with
a black pipe close nipple and collar, but overshot by inches, would rather not have to jack up radiator, any suggestions on where to find a suitable replacement ?

    The supply pipe couldn't be pulled up huh? I must be lucky, all mine have had lots of slack (probably from my house settling 4 inches LOL)

    You can try finding a extension nipple. It adds about an inch. Might have to raise the radiator up. 
    But then as @ethicalpaul mentioned, you can usually get enough play out of the pipe if you pull up on it.

    You did replace the spud in the radiator with the one from the new valve, I hope?

    I once cut the legs on a radiator to account for about a 1/2" difference that had few other easy options. It worked and looked good - even used 4 furniture cups and you'd never know.

    yes I managed to get the spud out of the radiator without breaking it, guess I am doing it again, I have found and ordered a marsh R-100A that has the crucial matching measurement from the bottom of the valve to the to the middle of the angle (1 3/4) Marshes are several times as expensive but reportedly nice. thank all for valuable input. I am interested in restoring the old one for possible redeployment, looks like the washer is toast
