Description

When you’re working on hydraulic systems, having the right adapter can make or break your day. This straight-through fitting bridges the gap between different thread types, letting you connect 1/8 inch male NPTF threads to 1/4 inch female NPSM threads without any headaches. The swivel connection means you don’t have to twist both sides to tighten it up—one end stays put while the other spins freely.

What You’re Getting

Straight design keeps your hydraulic lines running clean without unnecessary bends
Swivel female end rotates freely, making installation much easier in tight spots
5000 PSI working pressure rating handles serious hydraulic applications
11/16 inch hex on both ends gives you plenty of grip for wrenching
Converts between NPTF and NPSM thread standards seamlessly

Built for Real Farm Work

This adapter is perfect for connecting hydraulic components on tractors, implements, and other farm equipment where you need to mate different thread types. Whether you’re plumbing a new hydraulic motor, connecting gauge lines, or adapting aftermarket components to OEM fittings, this little fitting does the job reliably.

Made to Last

AgSmart builds these adapters to handle the pressure and vibration that comes with hydraulic work. The steel construction won’t crack or strip under normal use, and the precision threads ensure a leak-free connection that stays tight through temperature changes and equipment operation.

Good to Know

Use thread sealant or tape on the NPTF (tapered) male end, but don’t overdo it—just enough to fill the threads. The NPSM female end has straight threads and seals with an O-ring or gasket, so no sealant needed there. Always check your pressure ratings before installation and make sure this fitting matches your system’s requirements.
