I have been looking at fuel-line fittings and adapters.

I know what N.P.T. is; but, I am also seeing M.P.T. and F.P.T.

What are M.P.T. and F.P.T. ??

Thanks.

 

MPT = Male Pipe Thread
FPT = Female Pipe Thread

 

You mean like plain old N.P.T., just male or female ??

I wonder when it would have came to me.

 

Yes........

 

I was trying to find an adaptor for my compressor the other day and was puzzled by MIP and FIP. I'm guessing I now know what that M and F are for, but what about the IP?? Love this site, so informational, yet anonymous enough that I don't feel like

 

If the threads are on the interior, the fitting is female. If the threads are on the exterior, the fitting is male.

IPS means Iron Pipe Size, and also refers to threaded pipe.

MIP means Male Iron Pipe size. It refers to a male threading that will fit an IPS pipe.

FIP means Female Iron Pipe size. It refers to a female threading that will fit an IPS pipe.

 

Are IPS and NPT the same ??

Thanks.

 

I believe IPS is a straight thread (Like a bolt) and usually requires sealer.
NPT is a tapered thread.
