Question by: Cheryl H on Jan 25, 2026, 9:28 AM
got a hose end that’s 3/4-16 JIC, and the port on the block is 1-5/16-12 ORB. is this the straight adapter to tie those together?
Answer by: Customer Support on Jan 27, 2026, 7:59 AM
For tying those two ends together, this adapter is a straight male SAE O-Ring Boss (1-5/16-12) on one side and a male JIC 37 degree flare (3/4-16) on the other.

Will this adapter work for connecting a 1-5/16-12 male SAE O-ring boss to a 3/4-16 male JIC 37 degree flare?
Answer by: Customer Support on Sep 18, 2025, 7:11 AM
Yes, that's exactly what this Eaton Aeroquip adapter is designed for – connecting a 1-5/16-12 male SAE O-ring boss (straight thread O-ring) to a 3/4-16 male JIC 37 degree flare.
Question by: Dean B on Oct 13, 2025, 7:34 AM
Got a port on my hydraulic manifold that's 1-5/16-12 ORB and need to run a JIC line off it. This the right adapter for that?
Answer by: Customer Support on Oct 15, 2025, 6:42 AM
That's exactly what this fitting is built for. One end is a 1-5/16-12 male SAE O-Ring Boss, the other is a 3/4-16 male JIC 37 degree flare, and it runs straight through with no angle. The O-ring boss end seals against the port face, so as long as your manifold has that thread size and accepts a male ORB fitting, you're good to go.
Question by: Rex R on Jul 17, 2025, 7:32 PM
trying to match up a fitting i pulled off a hose, is this the one that goes from 1-5/16-12 male ORB over to a 3/4-16 male JIC 37 flare?
Answer by: Customer Support on Jul 19, 2025, 6:12 AM
Matches that setup. It is a straight steel adapter with a 1-5/16-12 male SAE O-ring boss (straight thread O-ring) on one end and a 3/4-16 male JIC 37 degree flare on the other.
