Description
When you’re working on hydraulic systems, there’s nothing more frustrating than having mismatched thread types that won’t connect. This adapter fitting solves that problem by converting a 9/16-18 OFS female connection to a 7/16-20 JIC male, letting you connect different hydraulic components without hunting for extra fittings or jury-rigging connections that might leak under pressure.
What You’re Getting
- Swivel design lets you position fittings without binding or stress on the threads
- 7500 PSI operating pressure rating handles demanding hydraulic applications
- Precision-machined threads ensure leak-free connections that stay tight
- Steel construction stands up to pressure cycles and temperature swings
- Direct thread-on installation with standard hex wrench flats for easy tightening
Built for Real Farm Work
This fitting works anywhere you need to connect OFS and JIC threaded hydraulic components. You’ll find these thread types on hydraulic cylinders, valves, pumps, and auxiliary circuits across different tractor brands and implements. Whether you’re plumbing a new hydraulic motor, repairing damaged lines, or adapting aftermarket components to your existing system, this adapter handles the job without adding bulk or weak points.
Made to Last
Hydraulic fittings take a beating from constant pressure, vibration, and temperature changes. This adapter is built with quality steel construction that handles the high pressures and torque requirements of hydraulic systems. The precision threads and swivel design reduce stress concentrations that can cause premature failure, keeping your system running when there’s work to do.
Good to Know
Install the OFS female end first, then connect your JIC fitting to the male end. The swivel action means you can position the connection without over-tightening or binding the threads. Use a 5/8″ wrench on the hex and an 11/16″ wrench on the nut hex for proper installation torque.
