5052 is the preferred alloy for fuel lines, much stronger than 3003, better in fatigue, and still easy to bend and flare, but more costly. For complicated runs, I make a trial fit with cheap readily available 3003 , then the final with 5052. I have ordered this a few times in 6 or 12 foot lengths, and have allowed it to be coiled to save shipping. Unfortunately, it came coiled (less desireable) but A/C spruces computer doesnt seem to reduce the shipping back down from oversize charges. (So you might want to inquire how to actually save shipping, if you go that route. Doesnt seem automatic.
This fitting works great for intended purpose, but I inserted a three inch tapered steel rod to make a mandrel for -4 303 hose terminals.

AN816 nipple fittings are straight NPT at one end and 37 degree flared at the other. All types of AN816 are 37 degree flare.
Correct, AN816-6D has 9/16-18UNF 37* flare thread on one end, and 1/4" NPT on the other end.
Please enter the quantity desired in the input box for each size and material, then click add to cart. The system will then add all of the items you requested into your shopping cart.
The AN816-8D will have two types of threads. One end wilL have 1/2 tube OD in which will be a 3/4-16 thread and the other end is a 3/8 NPT.
That would be an AN822.
This could be used with a rubber hose like a 303 but you would need to install the 491 fittings on the hose.
