got a 1" NPT port on a hydraulic manifold and need to swing the line out at 45 degrees, this the right adapter for that?
Answer by: Customer Support on Jul 28, 2025, 6:46 AM
that setup is exactly what this fitting handles. One end is 1-11/2 Male NPT, the other is 1-5/16-12 Male SAE 45 degree Flare, and the body bends at 45 degrees so you can redirect the line without adding extra fittings. It's part of Eaton Aeroquip's 2023 Series, catalog number C1AV71, so you're getting a name-brand steel adapter built for real industrial work.

trying to hook a pipe thread port to a JIC line with a 90, is this the right elbow for that?
Answer by: Customer Support on Feb 16, 2026, 10:22 AM
Built for that exact transition, it’s a 45 degree elbow adapter with a male NPT pipe thread on one end (1-11-1/2) and a male SAE 37 degree flare JIC on the other (1-5/16-12).
