Description
When you’re plumbing hydraulic systems or making repairs, you know that getting the right connection between different thread types can make or break the job. This straight adapter bridges the gap between 3/4-16 Male ORB and 1/2-14 Female NPSM threads, letting you connect components that wouldn’t otherwise fit together. It’s one of those handy pieces that saves you a trip to town when you’re in the middle of a hydraulic project.
What You’re Getting
- Swivel design on the female end reduces stress on hydraulic lines during installation
- 3500 PSI operating pressure rating handles demanding agricultural hydraulic systems
- 7/8 inch hex body gives you good grip for wrench installation without over-tightening
- AgSmart quality construction built specifically for farm and ranch applications
- Direct thread-to-thread adapter eliminates the need for multiple fittings
Built for Real Farm Work
This adapter works in hydraulic systems across all brands of agricultural equipment where you need to connect ORB (O-Ring Boss) fittings to NPSM (National Pipe Straight Mechanical) threads. You’ll find this combination on everything from loader hydraulics to implement connections, especially when mixing OEM and aftermarket components or adapting newer fittings to older equipment.
Made to Last
The 3500 PSI rating means this adapter can handle the high pressures found in modern tractor hydraulic systems without breaking a sweat. The swivel feature reduces wear on hydraulic hoses by eliminating the need to twist lines during installation, which extends the life of your entire hydraulic setup.
Installation Notes
The ORB side requires an O-ring for proper sealing – make sure you have the right size on hand before starting your project. Use thread sealant on the NPSM threads, but avoid tape that can contaminate your hydraulic system. The swivel end should turn freely after installation to prevent stress on your hydraulic lines.
