When you’re putting together hydraulic lines, fuel systems, or air connections on your tractor, you need fittings that won’t let you down when the pressure’s on. This 4-inch black iron nipple gives you a reliable threaded connection between two female-threaded components, whether you’re extending a hydraulic line to clear the frame or connecting fuel system components that need some extra length between fittings.
What You’re Getting
- Male threads on both ends (MNPT) for connecting two female-threaded fittings or components
- 4-inch length provides the extra reach you need for proper routing and clearance
- Black iron construction stands up to hydraulic pressure, fuel, and farm chemicals without corroding
- Standard 1/2-inch pipe thread size fits most common tractor hydraulic and fuel system applications
- Heavy-duty construction handles vibration and pressure cycles that come with daily farm work
Built for Real Farm Work
This fitting works great in hydraulic systems where you need to extend lines around the engine, transmission, or implement mounting points. It’s also perfect for fuel system repairs where you need to bridge the gap between the tank and injection pump, or when installing aftermarket fuel filters and water separators that require custom line routing.
Made to Last
Black iron pipe fittings have been the go-to choice for farm hydraulics and fuel systems for good reason. The material resists corrosion from hydraulic fluid and diesel fuel, while the solid construction handles the pressure and temperature swings that come with hard farm work. These fittings don’t crack under pressure like some cheaper alternatives might.
Installation Notes
Use pipe thread sealant or Teflon tape on the threads to prevent leaks – hydraulic systems especially need tight connections. Don’t over-tighten as this can crack female fittings, but make sure it’s snug enough to seal properly. A good rule of thumb is hand-tight plus one to two turns with a wrench.
