Description
When you’re working on hydraulic systems and need to connect two different thread sizes, this adapter is exactly what you need to bridge the gap. Whether you’re hooking up a gauge, connecting remote lines, or adapting between different hydraulic components, this fitting takes the guesswork out of mismatched threads and keeps your hydraulics flowing properly.
What You’re Getting
- Straight design that connects 3/8-18 NPT threads to 1/4-18 NPT threads without any bends or turns
- 6000 PSI operating pressure rating that handles the demands of modern tractor hydraulic systems
- 3/4 inch hex size that gives you plenty of grip when tightening with standard wrenches
- Male-to-male configuration that works between female ports on different components
Built for Real Farm Work
This adapter fits right into the hydraulic systems on tractors and equipment where you need to connect components with different thread sizes. Whether you’re adding a pressure gauge to monitor system performance, connecting hydraulic lines on implements, or adapting between newer and older hydraulic components, this fitting handles the job without restricting flow.
Made to Last
Built to AgSmart quality standards, this adapter is designed to handle the constant pressure and vibration that comes with hydraulic operation on farm equipment. The steel construction resists wear and corrosion, while the precision threads ensure a leak-free connection that stays tight even with the bumps and jolts of field work.
Installation Notes
This is a straight thread-to-thread adapter that installs just like any hydraulic fitting. Always use proper hydraulic thread sealant – never just tape that can contaminate your system. Make sure both connection points are clean before installation, and tighten to the proper torque specification without over-tightening.
