Product Questions & Answers (2)

Question by: Carl R on Oct 18, 2025, 8:07 PM
Trying to swap out an old fitting, is this one the straight adapter that goes from 1-7/16-12 male SAE O-ring face seal over to 3/4-14 male NPT?
Answer by: Customer Support on Oct 20, 2025, 3:58 PM
For a straight ORS to NPT hookup, this part matches those exact end connections: 1-7/16-12 male SAE O-ring face seal on one end and 3/4-14 male NPT on the other. It is a steel Eaton Aeroquip FF2031T Series adapter (SKU FF2031T1612S).
Question by: Hubert A on Sep 11, 2025, 1:19 PM
Got a hydraulic line on a piece of equipment that's got a 3/4-14 NPT port and I need to tie into a system running SAE O-Ring Face Seal fittings. This adapter do the trick for something like that?
Answer by: Customer Support on Sep 12, 2025, 1:58 PM
That's what this adapter is built for. One end is 1-7/16-12 Male SAE O-Ring Face Seal and the other is 3/4-14 Male NPT, straight configuration. So if your port is female NPT and your mating fitting is female ORS, you're connecting the two with this piece in between. It's part of Eaton Aeroquip's FF2031T Series, so it's a production-grade fitting, not a one-off solution.
