Question by: Floyd W on Aug 3, 2025, 8:23 PM
got a hose end that’s 9/16-18 JIC, what’s on the other side of this adapter?
Answer by: Customer Support on Aug 5, 2025, 2:39 PM
On the other end you get a 7/16-20 male SAE O-ring boss (straight thread O-ring) connection, so it bridges male JIC 37 degree flare to male SAE ORB.

Question by: Larry C on Jul 30, 2025, 6:04 PM
i got a hose end that’s 9/16-18 JIC male, and the port i need to hit is 7/16-20 ORB. Is this the right adapter to tie those together?
Answer by: Customer Support on Aug 1, 2025, 9:06 AM
Function-wise, it’s a straight steel adapter that bridges a 7/16-20 male SAE O-ring boss (straight thread O-ring) end to a 9/16-18 male JIC 37 degree flare end. If those are the two thread types and sizes you’re trying to connect, this part matches that combo.
Question by: Kirk G on May 10, 2025, 6:52 AM
Got a port on my hydraulic manifold that's 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 May 11, 2025, 8:44 AM
That's the use case this one covers. The male ORB end threads into a straight-thread O-ring boss port, and the male JIC end connects to a 37-degree flare fitting on your hose or line. Both connections are on a straight body, so no angle changes, just a clean inline transition between the two thread types.
