i'm pretty familiar w/ standard and metric threads and how to identify them...but what about these "-an" fittings. the place i see them the most is in my summit catalog on the fuel fitting stuff. what's different about them, and do they make a guage to id. them?

tia,

"AN" meaning army/navy where the first user's to spec em, year's ago.

They are a straight thread like a 37* JIC fitting but they won't interchange.

I don't know if anyone make's a gauge to measure the thread count, ask at a local hydraulic supplier, they carry them too. /forums/images/graemlins/grin.gif

-4 is ~4/16ths etc

are you sure they arent a swap for 37* JIC?

E-town baby!
-4,-6,-8 etc is the hose size in 16th's, doesn't tell you much about the thread itself. I can't recall if JIC threads match up or not, but i know JIC won't seal up to AN stuff.

JIC
-02 5/16-24
-03 3/8-24
-04 7/16-20
-05 1/2-20
-06 9/16-18
-08 3/4-16
-10 7/8-14

JIC and AN look the same to me
they share thread size, pitch, and flare angles
the hydraulic companies use the terms interchangeably IIRC
if you can find a -6 JIC to -6 AN adapter please shoot me a link, I love to learn

I used Goodridge and Aeroquip AN adapter fittings recently and the JIC seems to be sealing pretty good on them

JIC has a looser fit thread than AN spec fittings. All the dimensions are the same (AFAIK) but held to looser tolerances. I have heard that up to -6 there is no problem but when you get into the higher sizes (a friend was using -12 on his shocks /forums/images/graemlins/eek.gif) that the JIC won't seal.

JIC is 37 degrees in both male/female end's. Female cap to a male fitting. Or female nut [on say a 45 degree fitting] to a male fitting. /forums/images/graemlins/grin.gif
