Thread on one end is 1/2-20 ORB female and the other's 3/8-18 NPTF male -- that right? Just wanna make sure before I go pulling lines apart on this machine.

That's what you've got. The female end is a 1/2-20 SAE O-Ring Boss conforming to SAE J514, and the male end is a 3/8-18 NPTF per SAE J476. Brennan's part number on this one is 6404-05-06, so as long as your ports match those thread sizes and types, you're good to go.

got a valve block with a 1/2-20 ORB port. is this the piece that’ll adapt it over to 3/8-18 pipe thread?
Answer by: Customer Support on Jul 1, 2025, 9:08 AM
For that setup, it matches up. One end is a 1/2-20 female SAE O-Ring Boss (SAE J514) and the other end is a 3/8-18 male NPTF (SAE J476), so it’s made to transition from an ORB connection to a pipe thread connection.

Reckon this fitting will hold up okay in a hydraulic system running at, say, 2000 PSI? Don't wanna have no leaks.

Constraint-first: While the adapter's material is high-quality steel known for robustness, specific pressure ratings aren't provided. It's best practice to verify compatibility with your system's pressure demands to prevent issues.
