Description
When you’re building hydraulic lines or adapting different fitting types on your equipment, nothing beats having the right adapter to make the connection leak-proof and secure. This straight adapter connects a 1 5/8-12 Male JIC fitting to a 1 1/4-11 1/2 Male NPTF fitting, letting you bridge between JIC and NPT systems without custom hoses or complicated workarounds.
What You’re Getting
- Heavy-duty steel construction that handles 3000 PSI operating pressure
- Straight design keeps your hydraulic lines clean and efficient
- 1-11/16 inch hex makes installation easy with standard wrenches
- Direct connection between JIC and NPTF threads eliminates potential leak points
- Quality AgSmart manufacturing ensures consistent threads and reliable sealing
Built for Real Farm Work
This adapter works great when you’re connecting hydraulic cylinders, pumps, or valves that have different thread types. Whether you’re building custom hydraulic systems for implements, repairing equipment with mixed fitting types, or adapting aftermarket components to your tractor’s hydraulic system, this fitting bridges the gap between JIC and NPT connections reliably.
Made to Last
Farm hydraulics operate under demanding conditions, and this adapter is built to handle high pressure, vibration, and temperature changes. The steel construction and precision machining ensure the threads stay sharp and the connection stays tight, even after countless heating and cooling cycles.
Installation Notes
Use proper hydraulic thread sealant on the NPTF side – that’s the tapered thread that creates the seal. The JIC side uses an O-ring or flare seal, so don’t over-tighten. Clean both fittings thoroughly before assembly to prevent contamination in your hydraulic system.
