Working on a Tuban Fount and an Akron "Model 91" Burner.  Problem is dealing ithe 1/8" Pipe Threads without forcing or boogering the various valves and such.  Light came on when Dean mentioned that 1/8" SS is the non-tapered version of the 1/8"NPT dies. 

I was trying to duplicate the long taper on the Turban Fount that transitioned to straight threads (all 27tpi) and thought of a project.  Have a 1/8" NPT and 1/8" SS die.  OD on the brass pipe is 0.405".  Plan was to run the NPT die down and then the SS die.  Other end was SS first and NPT second.

I saw no difference - wondered what has happened!  I was unable to dublicate the long taper, but believe both ends of the pipe will seal.  Not tested yet.  Taper is "really small".

Looked up the dimensions, and yes - quite small!

Table below shows about 0.01" difference between the Pitch Diameter for Standard Threads and the narrow end of the Pipe Threads.  WOW!  not too much to work with!

Here is what I have.  Will do some testing.

I've done similar threading jobs for Akron/Coleman franks.  Usually just need lots of cutting oil and run the pipe tap or die deeper than usual.

Thanks - I've pretty much come to the conclusion that you are right!  Just don't want to booger the valve threads.  Will do a bit of testing and move forward.  Nice to have the internet to get odd taps and dies at decent prices to play!

Mike, pardon me for what is probably an ignorant question, but what does "spearmint" mean in the thread title?

Ohhhhhhhh, OK, Mike, I thought it was just another thing I'm just not knowledgeable about.  Just never heard that word in threads about taps and dies and such...🙂

Be careful running that NPT die too deep. It's easy to thread the fitting to the point that the nipple bottoms out before it seals in the female threads. Been there, done that. I usually take the die down to about halfway, then start test fitting it on the fitting I'll be threading it into.

I hadn't thought of using a straight die to extend the threads for locknuts, etc--seems like it should work.
It's priceless until someone puts a price on it.
