Product Questions & Answers (1)
Question by: Jerry P on Mar 2, 2026, 7:57 PM
got a port on a small hydraulic manifold that's 1/8 NPT and I need to tie into a #6 ORB line, this the right piece for that?
Answer by: Customer Support on Mar 4, 2026, 7:52 AM
That's exactly the conversion this adapter handles. One end is 9/16-18 male SAE O-Ring Boss, which is your #6 ORB, and the other end is 1/8-27 male NPT. Steel construction, straight configuration, so if your manifold has a female 1/8 NPT port and your line terminates in a female #6 ORB fitting, you'd be set.
