Description

If you’ve ever had a hydraulic line start weeping or noticed fittings working loose on your tractor, you know how important a properly tightened tube nut is. This 3/8 OFS steel tube nut gives you the secure connection you need to keep hydraulic fluid where it belongs—powering your equipment, not making a mess on the ground.

What You’re Getting

3/8 OFS size with 11/16-16 thread for secure hydraulic line connections
Steel construction that won’t crack or strip under the high pressures of hydraulic systems
Precision threads ensure proper seal when mated with corresponding fittings
Standard OFS design works with hydraulic tubing and fittings across multiple tractor brands

Built for Real Farm Work

This tube nut is designed for the hydraulic systems that keep your tractor working—loader circuits, remote hydraulics for implements, steering systems, and transmission lines. Whether you’re running hydraulics on a compact utility tractor or a full-size row-crop machine, proper tube nuts are what keep everything connected and leak-free.

Made to Last

Steel construction handles the constant pressure cycles and vibration that hydraulic systems dish out. This nut won’t work loose like cheaper alternatives, and the precision threads ensure a proper seal every time you tighten it down.

Good to Know

When installing, thread it on hand-tight first, then use a properly sized wrench to tighten to specification. Over-tightening can damage the fitting or tubing, while under-tightening leads to leaks. Keep a few spares on hand—hydraulic repairs always seem to happen when you need the tractor most.
