I have to make these handy little pics casue im always messing up what all the sizes are and then when i adapt etc...
Scawfish is dead on ! AN stuff rules.
soapbox....
Its a bit more $ up front, but once you learn the basics and learn what sizes you have/need you dont "waste" anything, I keep a supply handy to do general stuff, that and its easily repaired...
I order AN stuff from summitracing, speedway aka speedwaymotors.com and reciently from
http://www.anplumbing.com/ great $ on earls stuff,
I think people have preferences becasue thats what they have near then, have used before, or have been exposed to. For me its easier to order a pile of fittings and hose and build it, rather than take time off of work to goto a shop and explain to them what i want and have them do it for me..
happy plumbing...
