Weird Push Nipples (Pictures)

Sorry, I had to....but I've got some weird nipples.  You guys have given me some great advice on splitting the radiator sections and I finally got the sections apart but the nipples don't seem to be a standard size.

The crown measures 1.475 (so 1.5") which Oswald Supply doesn't seem to carry anymore.  

So what I think I'm going to do is just remove the next section which has a good nipple and reuse that one.

One question....what's the best way to clean the gunk out of the flange area?  I was thinking a mild cleaner/degreaser like Simple Green and a Scotchbrite pad.

Anyways, as promised....here are some pictures of my nipples.

Bad nip, salvaged nip.

A wire wheel on an electric drill will do the job just fine.

Yup!  Since replacement nipples aren't available I removed a section and salvaged a good nipple.  I used a nylon brush and some Simple Green then used a Scotchbrite pad and some steel wool.

Loaded up the flange with RTV and beat the snot out of it with a small sledge and a piece of wood to seat the sections together.

So far no leaks...
