Description
If you’ve been hunting for the right adapter to connect different hydraulic line sizes and thread types on your tractor or implements, this straight adapter gets the job done. It takes a 3/4-14 NPTF male connection and converts it to a 1/2-14 NPSM female swivel—perfect for those times when you need to adapt between different hydraulic systems or components that don’t quite match up.
What You’re Getting
- Straight-through design that maintains good flow and doesn’t add extra bends to your hydraulic system
- Female NPSM swivel end that rotates freely so you can position your lines exactly where they need to go
- Rated for 2200 PSI operating pressure—handles the demands of most tractor hydraulic systems
- 1-1/8″ hex on the body and 1″ hex on the swivel nut for easy installation with standard wrenches
Built for Real Farm Work
This type of adapter is commonly used when connecting hydraulic cylinders, valves, or pumps where the thread types don’t match up. You’ll find these connections on loaders, three-point hitches, and hydraulic remotes across various tractor brands and implement manufacturers.
Made to Last
AgSmart builds these adapters to handle the pressure spikes and vibration that come with hydraulic systems on working equipment. The threads are precisely machined to seal properly and the swivel mechanism stays smooth even after thousands of cycles.
Good to Know
When installing, thread the NPTF side in first (that’s the tapered thread that seals tight), then connect your swivel line to the NPSM side. A little pipe thread sealant on the NPTF threads helps ensure a leak-free connection. The swivel feature means you won’t have to fight twisted hydraulic lines during installation.
