When you’re plumbing hydraulic lines on farm equipment, sometimes you need to connect two male NPT threads together or extend a male connection through a panel or manifold. This straight adapter fitting does exactly that—it takes a 3/4-14 male NPT on one end and gives you another 3/4-14 male NPT on the other end, creating a solid connection that won’t leak under pressure.

What You’re Getting

  • Heavy-duty steel construction that handles the bumps and vibration of farm work
  • 5500 PSI working pressure rating for high-pressure hydraulic systems
  • Standard 3/4-14 NPT threads on both ends for universal compatibility
  • 1-1/8 inch hex flats for easy installation with standard wrenches
  • Straight-through design maintains consistent flow with minimal pressure drop

Built for Real Farm Work

This adapter is perfect for tractors, combines, and hydraulic implements where you need to join male NPT fittings or extend connections through equipment frames. Whether you’re plumbing a loader valve, connecting hydraulic motors, or setting up remote outlets, this fitting handles the high pressures and constant vibration that come with farm equipment.

Made to Last

Built from quality steel with precision threads, this fitting is designed to seal tight and stay that way. The 5500 PSI rating means it’ll handle even high-pressure systems without breaking a sweat, and the durable construction resists the corrosion and wear that comes from years of farm use.

Good to Know

Use good thread sealant or tape on both ends for a leak-free connection—hydraulic systems don’t forgive sloppy plumbing. The 1-1/8 inch hex makes installation straightforward with standard tools. When connecting to existing fittings, back off a quarter turn after hand-tight to avoid over-torquing and cracking the threads.
