AN fittings, how to measure?
Can somebody tell me how to measure AN fitting sizes? I have a friend with an AN fitting at home, but he doesn't know what size it is. He needs an AN to 1/8" pipe adapter for his WWII jeep. So if I tell him to "grab a ruler and do this....." what would the "do this..." part be. :)

I'm interested in hearing about this but I would guess the AN sizes are in millimeters.

scorp,
"16ths" so a -10 would be 10/16 or 5/8 and a -6 is 6/16 or 3/8 generally - numbers are even (4/6/8/10/12/16/20) BUT I have a -3 brakelines on my racer. Your best bet would be an Aeroquip catalog or a dealer because there is also the angle of the flare to think about. Perfomance AN fittings are 37degree who knows what they used in "the BIG one" WWll ...redvetracr |

Thanks, redvetracr. This might sound silly but where do you measure the 16ths from? Inner diameter of the line? Outer diameter?
Right now I am apt to tell him that he needs a -4 AN to 1/8 NPT from what you are telling me. |

Here's a link that should tell you everything you need to know.

Scorp another thing to be aware of is not all brands of hoses and fittings are interchangeable. I learned this the hard way for instance say you have a fitting by Russel and buy a hose from Earls you would think that if they were both the same size like say -4 they would fit but they don't. The id is the same but the od on the hose is different. Just though I would give you a heads up on that I bought some hose once that I couldn't use. :seeya

Black Bart - That is true even within the same brand. Aeroquip in particular has several series of hose ends, each designed for a specific series of hose. They are not interchangable.

scorp,
One more piece of (probably useless) info, 37degree is also known as "JIC" ...redvetracr |

#4 - 9/16" wrench - 1/4" od tube
#6 - 11/16" wrench - 5/16" od tube #8 - 15/16" wrench - 1/2" od tube #10 - 1 1/16" wrench - 5/8" od tube Don't kill me if the sizes are a little off. It's late, I have a few beers in me, and I'm working from memory. These are the most comon sizes I use at work on the airplanes. I also use these on my Vette. AN for aircraft does use a 37* flare. Trust me that an automotive 35* flare will seal just fine on aircraft fittings. I have them all over my Vette with no leaks. |

8 AN turned out to be 14/16. Which led me to this page which has really easy to use pictures.
