I'm just curious....

it's obviously wider that 1/8 " ???

why is this called 1/8" MIP then ?

thank you.

MIP is male iron pipe, which that isn't. Nor is it 1/8". Maybe I'm all wet. They've kind of made MIP interchangable with NPT, but that's not 1/8".It is just what has been accepted as 1/8" pipe. How's that for babbling?

Most importantly, the bag says nipple on it. :p

Dates back to when the only metal available(readily available?) for making pipe was cast iron. In order to get the pipe to withstand the pressures being used, the pipe wall needed to be very thick. So, as metal science evolved and stronger steel pipe became available, the need for the thick wall diminished, but a standard needed to created. It was decided that the "standard" OD, used the early thick walled cast iron pipe, would be kept and the ID would vary.

Because the i.d. is 'nominally' 1/8". Although that "looks" more like a 1/4" nipple.

all right . Thank you guys.

it is already so complicated to choose the right fittings, they should get rid of this nomenclature system IMO

thanks

And what would you replace it with? "I want a piece of pipe slightly smaller than my little finger"? A better question is "What were you doing that even needed a 1/8" nipple", because that is a very rare size.

I used one to make a dynamic pressure test apparatus for a sloan valve. It took a couple years to find one of the old style tops that has enough brass to thread into.

About real OD, real ID, and thread size..... wouldn't that makes more sense


thanks
