Product Questions & Answers (2)

Question by: Diane S on Jan 31, 2026, 6:14 PM
got a fitting with 1-11-1/2 male pipe threads on one side and a 1-5/8-12 male JIC on the other, is that what this adapter is?
Answer by: Customer Support on Feb 2, 2026, 2:15 PM
You’re describing the same thread setup as this part. It is a straight steel adapter with a 1-11-1/2 male NPTF end and a 1-5/8-12 male SAE 37 degree (JIC) flare end.
Question by: Harvey W on Nov 30, 2025, 8:48 PM
got a 1 NPT pipe thread on my manifold block and need to hook up a JIC 37 degree flare line, this adapter cover that transition straight through?
Answer by: Customer Support on Dec 2, 2025, 3:07 PM
That's exactly what this fitting handles. One end is 1-11/2 male NPT for the pipe side, and the other is 1-5/8-12 male JIC 37 degree flare for the hydraulic line connection. No elbow, no offset, just a straight through configuration. Steel construction keeps it solid in demanding hydraulic hydraulic connections setups, and it's part of the Eaton Aeroquip 2021 series which is well established in industrial and mobile hydraulic work.
