Question by: Rex A on Dec 5, 2025, 6:35 AM
Got a port on a hydraulic valve block that's SAE O-Ring Boss and I need to run a line off it with an ORFS fitting on the other end, this straight adapter the right call for that?
Answer by: Customer Support on Dec 6, 2025, 7:27 PM
That's exactly the scenario this fitting is built for. One end threads into a 1-1/16-12 SAE O-Ring Boss port, and the other side gives you a 1-3/16-12 Male ORFS connection to mate up with your line. Both thread types use O-ring sealing, so you get a clean, leak-free joint at each end without having to rely on tape or thread sealant. It runs straight through with no offset, so as long as your port orientation works with an in-line adapter, you're good to go.
