Got a line running 1-1/16-12 female JIC on one end and need to step down to a 7/8-14 male JIC on the other, this the right adapter for that?
Answer by: Customer Support on Dec 10, 2025, 6:34 AM
That's exactly what this one does. It connects a 1-1/16-12 female JIC 37 degree flare on one side to a 7/8-14 male JIC 37 degree flare on the other, in a straight configuration. Both ends use the same 37 degree flare seating, so the connection geometry is consistent across the joint. It's a reducer-style adapter, going from a size 12 female down to a size 10 male, and it's made from steel. Solid choice for that size transition in a hydraulic line.

It's designed for use in hydraulic, instrumentation, and chemical processing systems.
Question by: Wayne K on Oct 13, 2025, 2:14 PM
trying to hook a -12 female JIC line to a -10 male JIC, is this the straight adapter for that?
Answer by: Customer Support on Oct 14, 2025, 6:15 PM
For that kind of size change, yes. This part is a straight JIC 37 degree flare union with a 1-1/16-12 female JIC on one end and a 7/8-14 male JIC on the other, so it mates a -12 female JIC flare connection to a -10 male JIC flare connection.
