Product Questions & Answers (2)

Question by: Hubert P on Dec 19, 2025, 3:51 PM
got a 3/4-14 female pipe port on one side and need to land it into an SAE o-ring boss, is this the right adapter?
Answer by: Customer Support on Dec 21, 2025, 12:45 PM
For that hookup, it matches up as a straight steel adapter with a 3/4-14 female NPTF end on one side and a 1-1/16-12 male SAE O-ring boss (SAE ORB) on the other.
Question by: Earl B on Feb 13, 2026, 8:19 AM
got a 3/4 NPT female port on a pump manifold and need to tie into a 1-1/16-12 SAE O-ring boss fitting, this the right adapter for that?
Answer by: Customer Support on Feb 14, 2026, 7:32 PM
That's what this one's built for. One end is 3/4-14 female NPT and the other is 1-1/16-12 male SAE O-ring boss, straight configuration. It comes from the Eaton Aeroquip 2216 series, so the fit and thread quality are consistent with what you'd expect from that line. Steel construction holds up well in hydraulic hydraulic connections applications, and the SAE O-ring boss end gives you a cleaner, more reliable seal than a pipe thread alone.
