Description
Working with hydraulic systems means dealing with different thread types and sizes, and there’s nothing more frustrating than having the right hose but the wrong fitting when you need to get back to work. This straight adapter fitting bridges the gap between 9/16-18 male ORB and 1/4-18 female NPSM swivel threads, so you can connect your hydraulic lines without hunting down specialty adapters or dealing with leaky makeshift connections.
What You’re Getting
- Precision-machined straight adapter that connects different hydraulic thread standards
- Heavy-duty construction rated for 4000 PSI operating pressure
- Swivel feature on the female end reduces stress on hose connections
- 11/16 inch hex body provides secure grip for wrench installation
- AgSmart quality with clean machining that ensures leak-free sealing
Built for Real Farm Work
This adapter works across a wide range of agricultural and construction equipment where hydraulic systems use different fitting standards. Whether you’re connecting loader cylinders, three-point hitch systems, or hydraulic implements, this fitting handles the pressure and vibration that comes with farm work. It’s especially useful when retrofitting older equipment with newer hydraulic components or when custom hydraulic setups require thread adaptation.
Made to Last
Hydraulic fittings take constant pressure and temperature cycling, so this adapter is built from quality steel with precise threads that won’t strip or leak under load. The machining tolerances ensure proper O-ring sealing on the ORB side while the NPSM threads provide reliable pipe thread connections. It’ll handle years of hydraulic pressure without the seepage that cheaper fittings develop over time.
Good to Know
Thread the ORB side in by hand first to avoid cross-threading, then tighten with appropriate torque. Use thread sealant on the NPSM threads but avoid getting sealant on the ORB O-ring surface. The swivel feature means the female end can rotate freely, so position your hose routing before final tightening. Keep some penetrating oil handy if you need to remove it later – hydraulic fittings can get stubborn after years of service.
