Product Questions & Answers (1)

Question by: Warren G on Oct 14, 2025, 6:18 PM
got a port on a hydraulic manifold marked as 9/16-18 ORB and I need to run a line off it with an ORFS fitting on the hose end, will this adapter bridge that gap?
Answer by: Customer Support on Oct 16, 2025, 5:12 PM
That's exactly what this fitting handles. One end is 13/16-16 Male ORFS and the other is 9/16-18 Male ORB, so it'll connect your O-Ring Face Seal hose end to that ORB port in a straight inline configuration. Both thread types use o-ring sealing, which keeps things tight in high-pressure hydraulic circuits without relying on thread sealant or tape.
