Question by: Vince Y on Dec 4, 2025, 3:01 PM
got a line with 1-1/2 male pipe threads on it. is this the straight adapter that’ll get me over to a JIC flare?

It’s a straight steel pipe-to-flare adapter with a 1-1/2-11-1/2 male NPTF end on one side and a 1-5/16-12 male SAE 37 degree JIC flare end on the other.
Question by: Merle R on Jun 28, 2025, 9:20 PM
Got a 1-1/2 NPT male port on a pump manifold and need to step down to a 1-5/16-12 JIC male fitting. This the right adapter for that?
Answer by: Customer Support on Jun 29, 2025, 9:49 PM
That's exactly what this adapter is built for. One end is 1-1/2-11-1/2 Male NPT and the other is 1-5/16-12 Male JIC 37 degree flare, straight configuration. If your manifold has a female NPT port and your hose or tube end has a female JIC swivel, this will bridge that connection without any reducer or additional hardware in between.

got a hose end with 1-5/16-12 JIC on it, and the port i need to tie into is 1-1/2-11-1/2 NPT. is this the straight adapter for that?
Answer by: Customer Support on Apr 19, 2025, 5:53 PM
Matches that combo. One side is 1-1/2-11-1/2 male NPT (pipe thread) and the other side is 1-5/16-12 male JIC with a 37 degree flare, and it is a straight adapter in the Eaton Aeroquip 2021 series.
Question by: Dustin M on Jun 12, 2025, 9:54 AM
Will this adapter hold up in a marine environment? I'm dealing with saltwater exposure.
Answer by: Customer Support on Jun 13, 2025, 1:50 PM
Its applications include marine environments, so it should be suitable for saltwater exposure.
