Question by: Marvin E on Jun 10, 2025, 6:03 PM
Got a port on a small hydraulic manifold that's tapped 1/8 NPT and I need to hook into a -4 ORB line. this the right adapter for that?
Answer by: Customer Support on Jun 12, 2025, 6:47 AM
that setup is exactly what this piece is built for. One end is a 7/16-20 male SAE O-Ring Boss, which is your standard -4 ORB size, and the other end is a 1/8-27 male NPT. So if your manifold port is female 1/8 NPT and your line fitting is female -4 ORB, this adapter bridges those two thread types straight through with no offset or angle.

Will this fitting work to connect a 7/16-20 male SAE O-ring to a 1/8-27 male NPT?
Answer by: Customer Support on Aug 15, 2025, 2:52 PM
Yes, that's exactly what this steel adapter is designed for, connecting those two thread types securely.
