Al, you're getting senile. AN-6 is 3/8" i.d., AN-8 is 1/2" i.d.
AN fittings are in 1/16" increments, AN-6 is 6/16" or 3/8", AN-8 is 8/16".
SSDD= same $hit different day.
@dlearl476 I have those Dremel discs also. They work very well and the quick-change is great. They are pretty tough also, one disc will cut many hoses.
I usually buy the hose in 15-20 foot lengths, then I'll have extra for later if I mess one up for whatever reason.
