Product Questions & Answers (1)

Question by: Stan S on Jan 5, 2026, 9:32 PM
Got a hydraulic line running into a 1-1/4 NPT port on a pump manifold and need to tie in an ORS fitting on the other end. This adapter cover that situation?
Answer by: Customer Support on Jan 7, 2026, 6:08 AM
That's exactly what this one is built for. One end is a 1-11/16-12 male SAE O-Ring Face Seal and the other is a 1-1/4-11-1/2 male NPT, straight through with no angle. Both ends are male, so you'd need female threads on each port you're connecting to. Eaton Aeroquip makes these to tight tolerances, and the ORS end uses an o-ring to seal against a flat face, which keeps things leak-free under pressure without a lot of fuss during installation.
