Question by: Billy H on Nov 25, 2025, 8:10 PM

what's the thread size on this plug, and is it actually a JIC 37 degree flare fitting?

Answer by: Customer Support on Nov 27, 2025, 6:30 AM

Yes on both counts. The thread is 1-7/8-12, and it does use the standard 37 degree flare seating angle that JIC fittings are known for. It's part of the Eaton Aeroquip 900599 series, catalog number C1CB18, so you're getting a genuine Danfoss/Eaton straight adapter hex plug, not a generic substitute.
