Product Questions & Answers (1)

Question by: Lance H on Jan 19, 2026, 2:03 PM
got a 3/8 NPT female port on a hydraulic manifold and need to tie into a 7/8-14 ORB male fitting, this the right adapter for that?
Answer by: Customer Support on Jan 21, 2026, 6:48 AM
That's what this one's built for. The 3/8-18 female NPT side threads onto your manifold port, and the 7/8-14 male SAE O-Ring Boss end connects to your ORB fitting. Steel construction, straight configuration, no angled offset. It's a rigid adapter so there's no swivel or articulation involved, just a solid inline connection between those two thread types.
