Question by: Shane C on Apr 18, 2025, 1:20 PM
got a hose end with 1-7/8-12 JIC, is this just a straight union to hook two male flare ends together?
Answer by: Customer Support on Apr 20, 2025, 6:11 AM
Function-wise, it is a straight 37 degree flare union adapter that has a 1-7/8-12 male JIC (SAE 37) on both ends, so it joins two matching SAE 37 flare connections with the same thread size.

Got a union fitting that needs replacing on a hydraulic line running 1-7/8-12 JIC on both ends. this the right part for that?
Answer by: Customer Support on Mar 2, 2026, 3:45 PM
For a same-size JIC union connection, this is exactly what you'd want. Both ends are 1-7/8-12 Male JIC with a 37-degree flare, so it's built to join two female JIC ends of matching thread and flare spec in a straight configuration. Part of the Eaton Aeroquip 2027 Series, it covers hydraulic, instrumentation, and chemical processing lines, which covers most shop and field scenarios where that thread size comes up.
