Question by: Carl W on Feb 9, 2026, 5:36 PM
got a hose end that’s -6 JIC. will this adapter get me over to a 5/8-18 inverted flare without a bunch of extra stuff?

For tying those two styles together, it’s a straight adapter with a -06 male JIC 37 degree flare on one end and a 5/8-18 male 42 degree inverted flare on the other, so it’s meant to make that exact connection in one piece.

got a 37 degree JIC fitting on one end and need to tie into a 42 degree inverted flare on the other, this the right adapter for that?

That's what this one's built for. One end is a -06 male JIC with a 37-degree flare, the other is a 5/8-18 male with a 42-degree inverted flare. Straight configuration, no angle to it. Eaton Aeroquip makes it, catalog number C1ZY20, so you're getting a known name behind it.

I'm just trying to make sure this adapter will fit my setup. It's gotta go from a -06 JIC flare to a 5/8-18 inverted flare. Will it work?
Answer by: Customer Support on Jun 23, 2025, 9:52 PM
It adapts a -06 Male JIC 37-degree flare to a 5/8-18 Male 42-degree inverted flare, so if those are the connections you have, it should fit just fine.
