rad question...HW

Mike T., Swampeast MO

Really not difficult to remove the tapping bushing. Lay the radiator on its side, use a cheater bar on the biggest wrench you have and have couple people stand on the rad. I've removed MANY in this way and have never broken the rad.

So my helper, with the best of intentions, cut past the threads on two rads while extracting the brass nipples. Just past. They are 3/4". The dogs just broke off and the brass crumbled when we cut off the nut & applied a wrench. I am not opppsed to glueing the new nipples (unions) in, but do I epoxy, then re-thread or just polyurethane glue them in or JB weld? Any advise appreciated. Do not want to even try the 11/2-3/4 bushing. Old rads.

Is one of the tapping bushings going to be LH thread? I may have one from another rad. If not, then what? I should add that this rad is in a bedroom with all hardwood floors and a large bed. I would prefer to glue this in, but should be able to find enough room and a drop-cloth.

Thanks,

Tim

Every tapping bushing I've ever seen uses standard RH threads on the outside. The inside thread might be LH in very unusual circumstances--like when a union or valve tailpiece isn't screwed into it.

Modern black steel reducing bushings may not be decorative like some of the originals, but they're close to the same overall length--if not exactly the same if you find them from the right supplier. Even if they're a little longer you shouldn't have any problem unless there's utterly no play in the piping.

I had the same problem

a few weeks ago . We had to move a few rads around and couldn't get the brass union adapters out of the rads . They were 1/2 inch . We cut the threads flush with the bushing , then cut the sawzall blade down so it would fit in the hole . We cut 4 wedges into the remaining brass and punched them out with a screwdriver . Turned out to be the easiest part of the whole job .
