misterp Posted April 19, 2005 Report Share Posted April 19, 2005 AN = "Army/Navy", fittings employ a 37-degree flare seat (as opposed to hardware store SAE flare seat which is 45-degrees and not compatible). Hose diameter is sized in 1/16-inch increments, a #4AN hose (or tubing) has a 1/4-inch diameter, #6AN is 3/8-inch, #8AN is 1/2-inch, etc. Fittings and hoses are designed for extreme pressure and/or severe duty and are extensively used in aircraft industry and high-end automotive applications. And they're darned pretty! Mr. P. edit - I got the flare seat angles wrong the first time! Link to comment Share on other sites More sharing options...

Megashifter Posted April 19, 2005 Report Share Posted April 19, 2005 AN fittings have pretty much been replaced by MS (Mil Std) There are handbooks explaining each. Google it. Link to comment Share on other sites More sharing options...
Revenoor Posted April 21, 2005 Report Share Posted April 21, 2005 Take a look at Russell Performance http://www.russellperformance.com/tech_center/index.html Some AN and MS specifications are being re-identified as AS. Link to comment Share on other sites More sharing options...
