Question by: Freddie L on Jan 7, 2026, 6:37 PM
got a hose end thats 1-5/16-12 female JIC swivel, will this step it down to a 7/8-14 male JIC and still be a straight adapter?
Answer by: Customer Support on Jan 9, 2026, 6:57 AM
Built for exactly that reduction, it goes from a 1-5/16-12 female JIC 37 degree flare swivel end to a 7/8-14 male JIC 37 degree flare, and it is a straight reducer adapter in the Eaton Aeroquip 221501 series.
Question by: Clint S on Sep 21, 2025, 12:17 PM
Will this adapter work to connect a 1-5/16-12 female JIC to a 7/8-14 male JIC fitting?
Answer by: Customer Support on Sep 22, 2025, 1:44 PM
That's what it's for. It's a reducer adapter made to connect those two specific sizes of SAE 37 degree flare fittings.
Question by: Dale C on Dec 22, 2025, 5:49 PM
got a 1-5/16-12 female JIC port on a hydraulic block and need to step it down to a 7/8-14 male JIC line, this the right reducer for that?
Answer by: Customer Support on Dec 24, 2025, 5:22 PM
That's what this adapter is built for. The female end is 1-5/16-12 JIC 37 degree flare swivel, and the male end is 7/8-14 JIC 37 degree flare, so it bridges those two sizes in a straight configuration. Both sides use the same SAE 37 degree flare seating, so the connection geometry matches up clean on either end.
