I was looking into JIC fittings as an alternative to AN for a cheaper fuel setup that wont blow up in my face and found something kinda odd with the difference between fancy PTFE fittings and the standard hydraulic fittings. If you look at the links above, you'll see that the dimensions are the same... well, they're different, but it's only for the overall dimensions that don't matter. The only dimension they don't list is the diameter of the crimp casing. I looked up the OD for -8 100r14(PTFE) and SAE 100R1 hydraulic hose which were .63in for ptfe and .81in for the 100r14. If there is any difference, this must be it.... so i'm SOL and have to use ptfe fittings? maybe... I was looking at this ptfe fitting and it lists a standard hydraulic Weatherhead 08E-668 as an interchangable part. That weatherhead part also says it will work with PTFE hoses with a dia of .63in but also regular hydraulic hose with a .8in OD. Any advice here? It seems very likely they could handle the .17in difference in diameter since they're not removable and then I could use these $6.72 90deg fittings instead of the $16 summit parts. All the standard JIC fittings are about 1/3rd cheaper and i'm ok with crimping.
