Legend 1" Valve question

Can someone tell the reducing bushing size that will fit into where the valve stem would go? I went to fw webb they said it wasn't a 1.5" or a 1.25". I want to add a vent to the top of this valve.

Thanks for your help

    not that type of thread

    It does not line up with pipe thread. you can thread and tap the radiator if you are careful there should be another spot opposite the current vent. have you tried a larger vent on the radiator?
    Cost is what you spend , value is what you get.

  • extra venting for riser

    why not put a gorton "d" on the radiator in the usual vent tapping? the capacity is the same as a gorton #1 on a riser.

    the valve bonnet threads are not tapered like regular pipe threads, so no joy there.---nbc

    Drill & Tap size

    I see grotons come 1/8" or 1/4" for the 4,5,6,D models, can someone update my previous thread to these drill and tap sizes. I have vari vents now which i think are 1/8". do you measure the inside diameter of the vent hole itself?



    Thank You

  • extra venting

    just put the gorton on in place of the old vent, and see if there is improvement.--nbc

    Easier Fix

    Thanks nbc, your right, a larger vent is easier to install than drill and tapping steel.
