I have a 3/4 NPT fitting that broke off flush in a housing on the head of a Curtis Air compressor. It is a steel or case iron fitting.

I have seen a tool with an eccentric on the side of it made just to take out broken pipes. I have not had any luck finding it on line with out a better name/description.

I have easy-outs that size but the hole is not deep enough for them to bite the broke pipe.

I also thought about thinning the broken piece with a carbide cutter in a die grinder but really do not want all of the metal filings around the compressor head.

This compressor fell over while I was hauling it and broke several fittings. I have them all removed other than this one. I would rather not have to take the head off the compressor. This compressor is 40-50 years old and parts are hard/pricey to get.

I have broken of the small end of an easy out so the easy out dosen't have to go in so deep.

I saw 1/2 and 3/4 in Lowes about a week ago. I think they had other sizes also but I wasn't looking for any because I have a full set.

In an earlier life I would come across broken off 3/8 nipples regularly. I was able to just take the fairly large flat blade screwdriver that I carried in my box and tap it into the piece that was broken off in the other. I could then just slip my adjustable wrench over the upper part of the screwdriver and turn the broken piece right out.

And I've driven an appropriate sized allen wrench into flush broken pipe nipples. Along with Wayne's grease coated rag to catch any particles.

I was just at NAPA yesterday, I thought I saw a tool there that would do what you want. But you have already ordered one.

rankrank1: YOU got the name of the tool I was looking for. I could not remember what they where called. (internal pipe wrench) Kind of seems obvious now. DAAAAAAA LOL

I ordered a set from Proto. Should have them next week.

Thanks for the replies. I was drawing a complete blank.

Short of buying some more tools... and who doesn't like to do that there's only one way I know of to get a broken pipe nipple out. First, coat a hacksaw blade with grease, and put a piece of rag, also with a bit of grease on it, in the back of the hole to catch anything not caught on the blade. Then all you need to do is saw a kerf through one side of the fitting. From there take a cape chisel and bend the sides of the fitting toward the middle. Once folded in it should come right out. If it doesn't then make a cut 180 degrees from the first and then it should come out....never had one that didn't unless it was rusted in tight, and those just took a little longer. Good luck.

NCWayne: I have taken them out that way too. The trouble is that you damage the threads some when you do them that way. I am worried that since this is air and right on the compressor main high pressure line that it will leak.

I have a set of extractors from matco. They're like easy outs, but short and small size increases. I think there is like 25 in the set. I got them just for situations like you have. If you have a dealer around, I would ask about them. Tim

"internal pipe wrench" will be the name of the tool with the eccentric like you are inquiring about.

"pipe extractor" or "pipe nipple extractor" will be the name of the stubby easy out type of tool that is made specifically for pipe.
