Question by: Frank M on Mar 20, 2026, 7:46 AM

Got a #12 JIC line on a hydraulic manifold and need to tie into a system running ORFS fittings. This straight adapter gonna bridge that gap without me having to re-flare anything?

Answer by: Customer Support on Mar 21, 2026, 2:41 PM

That's exactly what this fitting is built for. One end is a 1-3/16-12 male O-ring face seal, the other is a 1-1/16-12 male JIC 37-degree flare. Both are #12 size, so you're connecting directly between those two thread standards without any modification to your existing lines. Steel construction holds up well in high-pressure hydraulic setups, and the ORFS end gives you a leak-free seal through the o-ring rather than relying on thread contact alone.
