push nipple

T_4T_4 Member Posts: 19
I took a single pipe steam radiator apart. The sections came apart easily. However half of the push nipple is stiil stuck in the section. How can I get the nipple out. I tried putting a wrench on it without success.

    Try...

    A slide hammer, or fabricate a wheel puller.

    Get a 6+" 1/2 bolt/threaded rod, put a "toggle" cross-piece inside the nipp and an oversized short nip (perhaps a 2"X close? around the push nipp hanging out - using the taller edge of the 2" X close as a base. Get a huge fender washer or like thingy to allow the bolt/rod to go thru with the toggle (perhaps a piece of channel/uni-strut) over drilled so it will "toggle" into the push nip and yet when drawn back, catch both side of the inner aspect of the push nipp.

    A washer or two, a nut, a deep socket or open end...

    Voila!

    How would I do this with a slide hammer?
    A couple of the nipples are stuck in end sections,
    so I can only get at it from the front.
    The nipples are in good condition, so I
    would like to salvage them. Thanks.

    The slide hammer I envision...

    Is the kind that has a screw-on steel "finger."

    Put the finger edge/lip on the inner shoulder of the P.N. and GENTLY slide the weight - using three opposing points to assure you don't cock the P.N. or crack the c.i.rad boss

    Want a photo of the slide hammer I use?

    Hi,

    Thanks for the photo, but I don't see how this tool will help. Perhaps I have not expalined properly.
    The radiator sections came apart, but the nipple is still
    attached to one of the sections. So let's say the nipple is 3"
    then 1 1/2 " is exposed. Now I tried puuting a wrench around the exposed parr of the nipple, but had no success.

    T,

    If the tool pictured appears to have no purpose for the job you have described and have at hand, perhaps you could send us a picture of what is there?

    The tip of the slide hammer would be inserted just far enough to have the small but very sturdy "lip" of the screw on adapter "finger" just snag the inner cicumference of the P.N. Once it is on that edge, the slide hammer would exert a "come-on-outta-there" force that would jar the P.N. out a tad with each stroke - until the taper became so loosened, it would come out the rest of the way by hand.

    If you do not see the merit of the tool, I don't understand the nature of your dilemma. A photo from you would be worth a thousand words...

    I'm not familiar with "slide hammers" and how they
    work. But I think I understand what you're suggesting.
    The nipple in question is a good 2" in diameter, so it seems
    hard to believe that this would work.
    Would a "Government surplus slide hammer, 13" oal, 1/2-20 nf thread, 2-1/2 lb hammer" suffice ? I can get this on ebay.
    Where would I find an appropriate finger tool attachment?
    Thanks

    Provided you can get at the other side of the nipple, use a big flat blade screwdriver and a hammer. Not too hard and keep working your way around the circumference of the nipple. I'd be a bit wary of re-using a nipple on which you've used a wrench as there's a great chance you've either scraped it up or distorted it and since they seal strictly by smooth metal-to-smooth metal contact...

    If you can't get at the other side, you might try a strap wrench
