    Fitting terms

     



    Ok, I'm am getting so confused on these fittings. Flared fittings, O ring fittings, AN fittings, pipe fittings.

    K, so I know what FPT and MPT is. So, what does NPT stand for?? And, what size NPT would fit a 3/4" FPT??? What the hell size is a #6 compared to a #8 AN fitting?? Someone enlighten me please!!!

    AN is measured in 1/16ths. Example. a -4 AN fitting is 1/4", a -8 is 1/2", -3 is 3/16", -2 is 1/8". Simple enough?

    Dean, I have been living your life daily. I got AN figured out as well with the 16s thing. But building a Cobra with Smith's guages, I also threw British Pipe thread into the mix. My head still hurts. The Aeroquip guy in town is going to send me a Season's Greeting card and I didn't set foot in there until Sept.

    P.S. Pegasus Racing has some real oddball adaptors.

    Dean,
    NPT = National Pipe Taper

    Here's a link to an aircraft oriented site that has several reference charts that might come in handy, not only for the fittings and cross referencing, but for a few other items.

    It's much easier to promise someone a "free" ride on the wagon than to urge them to pull it.

    Luck occurs when preparation and opportunity converge.
