got a 7/16-20 ORB port on my hydraulic manifold and need to run a JIC line off it, this the right adapter for that?
Answer by: Customer Support on Dec 18, 2025, 5:47 PM
That's what this one's made for. One end is a 7/16-20 male SAE O-Ring Boss, the other is a 1/2-20 male JIC 37-degree flare, straight configuration. No thread sealant needed on the ORB side since the o-ring does the sealing work. Just make sure your JIC line fitting is female to mate up correctly.
