Description
When you’re connecting hydraulic lines and components, having the right adapter can make all the difference between a clean, leak-free connection and a frustrating mess. This straight adapter bridges the gap between different thread types, converting a 1-11.5 inch male NPTF thread to a 1-11.5 inch female NPSM swivel connection. It’s the kind of fitting that saves your day when you’re trying to hook up hydraulic pumps, cylinders, or implement connections.
What You’re Getting
- Straight-through design maintains direct flow path for maximum efficiency
- Swivel female end rotates freely so you can position connections without twisting hoses
- 2000 PSI operating pressure rating handles high-pressure hydraulic systems
- 1-1/2 inch hex on both ends gives you plenty of grip for installation with standard wrenches
- Steel construction with AgSmart quality that stands up to farm conditions
Built for Real Farm Work
This adapter is designed for hydraulic systems on tractors, implements, and other farm equipment where you need to connect components with different thread specifications. Whether you’re plumbing a new hydraulic cylinder, connecting remote outlets, or adapting aftermarket components to your existing system, this fitting handles the job reliably.
Made to Last
Farm hydraulic systems see constant pressure cycles, vibration, and temperature changes. This adapter is built from quality steel with proper thread machining to ensure tight seals and long service life. The swivel design reduces stress on connections and hoses during operation.
Good to Know
The NPTF (National Pipe Thread Fuel) male end creates a metal-to-metal seal, while the NPSM (National Pipe Straight Mechanical) female swivel end uses an O-ring seal. Make sure you have the right O-ring for the NPSM connection. Use thread sealant on the NPTF threads for a proper seal, and don’t over-tighten—the 1-1/2 inch hex gives you plenty of leverage.
