got a hose end that’s 1-5/8-12 SAE o-ring boss and I need to tie into a 1-1/16-12 JIC flare. is that what this adapter does
Answer by: Customer Support on Mar 1, 2026, 3:49 PM
Built for exactly that connection, it goes from a 1-5/8-12 male SAE O-Ring Boss (straight thread O-ring) on one end to a 1-1/16-12 male JIC 37 degree flare on the other, in a straight adapter body.

Got a port on a hydraulic manifold that's 1-5/8-12 SAE O-ring boss and I need to run a JIC line off it, this the right adapter for that?
Answer by: Customer Support on Oct 24, 2025, 9:45 AM
That's exactly what this fitting is built for. One end is a 1-5/8-12 male SAE O-ring boss (straight thread), and the other is a 1-1/16-12 male JIC 37-degree flare. It makes a straight, inline connection between those two thread types without any angled offset. It's part of the Eaton Aeroquip 202702 series and made from steel, so it's got solid construction for typical hydraulic line work.

trying to hook a -20 SAE o-ring boss port to a -12 JIC line, is this the right adapter or am i mixing stuff up
Answer by: Customer Support on May 1, 2025, 2:37 PM
Function-wise, it’s the correct style for that job. One end is a 1-5/8-12 male SAE O-Ring Boss (straight thread O-ring boss) and the other end is a 1-1/16-12 male JIC 37 degree flare, and it’s a straight steel adapter.
