Question by: Phil C on Nov 5, 2025, 7:05 AM
Got a -06 JIC line I'm trying to tie in and need to confirm the flare angle on this nut before I order. It's 37 degrees, right?
Answer by: Customer Support on Nov 6, 2025, 3:49 PM
Correct, the AN 818 flare nut is built for 37-degree JIC flare connections at the -06 dash size. That's the standard angle used across most JIC tube fittings, so as long as your tube end and mating adapter are both -06 JIC 37-degree, this nut will pair up with them just fine.
