Product Questions & Answers

adapter goes from the bigger ORB port down to a JIC fitting, that right? trying to figure out if this'll work for a return line i'm hydraulic connections up
Question by: Glen M on Jan 15, 2026, 7:26 AM
That's exactly what it does. One end is a 1-1/16-12 male SAE O-Ring Boss and the other is a 7/16-20 male JIC 37 degree flare. The ORB side threads into a female ORB port, and the JIC side connects to a standard female JIC swivel or fitting. It runs straight through with no angle, so keep that in mind when you're figuring out your line routing.

Will this adapter hold up okay in a hydraulic system running around 3000 psi?
Question by: Floyd H on Oct 24, 2025, 12:45 PM
For hydraulic applications needing robust reliability, this steel adapter is a solid choice. It's designed to provide secure, leak-proof connections between SAE O-Ring Boss and JIC fittings, so it should handle that pressure.
