Question by: Sherry P on Feb 26, 2026, 1:34 PM
got a line with a 1/2-20 inverted flare on it, will this adapter let me step over to a 6 JIC male end?
Answer by: Customer Support on Feb 28, 2026, 7:33 AM
Fit wise, it is a straight brass adapter with a 1/2-20 male 42 degree inverted flare on one side and a 5/8-18 male SAE 45 degree flare (often called 6 JIC) on the other. It is also called an Eaton 5 M INV Flare 6 M JIC adapter, and it is listed for 0.38 inch OD tube size.
Question by: Terry H on Nov 27, 2025, 6:02 PM
got a 1/2-20 inverted flare line I'm trying to connect up to a 5/8-18 JIC fitting on a hydraulic system, will this adapter do the job or am I barkin up the wrong tree?
Answer by: Customer Support on Nov 29, 2025, 6:54 AM
That's exactly what this adapter is built for. One end is a 1/2-20 male 42 degree inverted flare and the other is a 5/8-18 male SAE 45 degree flare, so it bridges those two thread and flare standards in a straight configuration. It's made by Eaton Aeroquip and carries catalog number C1AU32 if you need to cross-reference it against your parts list.
