When you’re connecting hydraulic components with different thread types, you need an adapter that won’t leak or fail under pressure. This straight adapter converts from ORB (O-Ring Boss) to NPT threads, letting you connect modern hydraulic components to older systems or adapt between different manufacturer specifications. It’s the kind of fitting that keeps your hydraulic system running without drama.
What You’re Getting
- 4000 PSI operating pressure rating handles heavy-duty farm hydraulic systems
- Direct thread conversion eliminates the need for multiple fittings or modifications
- 1-3/8 inch hex provides solid grip for installation without damaging the fitting
- Precision-manufactured threads ensure leak-free connections that stay tight
- AgSmart quality construction built to handle the vibration and pressure cycles of farm equipment
Built for Real Farm Work
This adapter fits into hydraulic systems across all kinds of farm equipment where you need to connect ORB fittings to NPT threaded ports. Whether you’re plumbing hydraulic cylinders, connecting pressure lines to valves, or adapting aftermarket components to OEM systems, this fitting handles the conversion cleanly. It’s especially handy when retrofitting newer hydraulic components onto older tractors or implements.
Made to Last
Farm hydraulic systems are tough on fittings, with constant pressure cycles, vibration, and exposure to weather. This adapter is built with quality materials that resist corrosion and maintain their seal integrity through thousands of pressure cycles. The precision threading ensures a solid connection that won’t work loose or develop leaks over time.
Installation Notes
Use proper thread sealant on the NPT side and make sure the O-ring is in good shape on the ORB connection. Don’t overtighten—the ORB side seals with the O-ring, not thread torque. If you’re working in tight spaces, that 1-3/8 inch hex gives you good wrench purchase without needing special tools.
