I came across a fitting that I have never seen before. The guy who used it picked iy up at work. He is either a coal miner or works in a steel mill. The fitting is used to connect RMC together. One end had the regular male threads the other end had very fine female threads. He told me that you just screw the very fine female thread end onto a piece of nonthreaded RMC.

He was installing a mast for a service which was 14 feet tall. He had a4 foot piece of RMC with factory thread on one end the other end was not threaded. He screwed this fitting into the meter hub. He then screwed the nonthreaed end of the RMC into the very fine female threads of this fitting. It seamed to work.

If anyone knows any more information about this fitting please let me know. I could not see any markings on that fitting.

Thanks.

SEO, No I did not look at the UL book. As a matter of fact I did not even think of looking there but I will now, thanks.

I am headed out of the office for the rest of the day and i will check back later to see if anyone else had any information for me.

As you can see I am still in the office. This fitting was not a compression type. The conduit was just threaded into the fine threads of that fitting. Again thanks for the information.
 
From the description it sounds like an OZ-Gedney Threadmaker fitting.

Maybe a Crouss-Hinds fitting.

I have used them years ago at a treatment plant.
 
TkB, Thanks for the information. I tried to look up fitting on those web sites yesterday, but I could not find them. Now that I know the name I will try again. Thanks for the information.

Sounds like Mertic/ANSI converter.
 
I want to thank everyone who responded. I went to all of the web sites that you mentioned but I was still unable to find that fitting. If anyone can find anymore information on this fitting it will be very helpful.

Thanks Again, Bill
 
I tried to find it myself.
I dont think it is still made anymore.
I will look in some of my old catalogs.
I know it existed.
 
Doesn't sound like a very raintight fitting, especially when you're using it above a meter. Not saying a threadless connector is any better though.
 
never heard of it ...you sure it was listed as an electrical fitting
seen guys using plumbing fittings before..
threadless connectors were set screw or compression i thought
although arlington ind comes up with nifty stuff...
 
Hi. I know nothing about this fitting. I inspected the job and would like to find out if this is an electrical fitting. I asked the contractor and he said he uses them all of the time. I did pass it this time but if i find out it was not an listed electrical fitting, I will not trust that contractor any more.

I know it was an electrical fitting at one time.

It had a fine female tapered thread on one end that would screw onto a cut unthreaded rigid conduit, and the other end had either male or female NPT threads.

I know it was either OZ-Gedney or Crouse-Hinds.
 
Tkb, You described it perfectly. I looked on both of those manufacturers web sites and i could find nothing, I looked at the fitting but i did not see any markings. When I run into him again I have him give me more information on them. He too also thought that OZ-Gedney or Crouse-Hinds made them.
 
I think it also has hex flats in the center of the coupling so you could tighten it.

I am trying to find an old catalog in my junk, just to prove that I am not crazy.
I know it existed.
 
I found it

I found it

tkb, you were correct it was a Threadmaker Fitting. This one was Crouse-Hinds. The contractor brought me in one and I was able to track it downnusing the marking on the fitting. I went to their web sit and found this.http://www.crouse-hinds.com/CrouseHinds/InstallationDocs/IF489.pdf. It looks like you will have to do a cut and paste to get to this site.

Thanks again for everyone who responded

I couldn't find anything on it.
Thanks for posting the link. Now I know I'm not crazy.

Do they still make this fitting?
