[quote name='chevy350' post='337972' date='23/2/2011, 19:45']questa ? la spiegazione/traduzione di "AN" che ho trovato su un sito vette:



Hi,

I try to explain my request.I try my best.

When I see in some catalogue the plumbing section I find two tipe of size:

3/8'',1/2'',5/8'' etc..

and :

-4AN,-6AN,-8AN etc..

Someone can post some conversion table between the two different size?





AN stands for Army/Navy and is a MILSPEC standard. It is the hose diameter in 1/16" So a -4AN would be 4/16 or 1/4". -6AN would be 6/16 or 3/8" and so on.



Also AN flare fittings us a unique 37 degree single flare.



Each -AN size is a multiple of 1/16"



For example:



-8AN = 1/2" (-8 = 8 x 1/16" = 8/16" = 1/2")



-6AN = 3/8" (-6 = 6 x 1/16" = 6/16" = 3/8")[/quote]

questa non la sapevo,

grazie chevy 350
