Description
When you’re working on hydraulic lines, a secure connection can mean the difference between a productive day in the field and an expensive breakdown. This 1/2 OFS tube nut with its 13/16-16 thread gives you the reliable seal you need to keep hydraulic fluid where it belongs—powering your equipment, not leaking onto the ground.
What You’re Getting
- Precision 13/16-16 threading that matches OFS (O-ring Face Seal) fittings perfectly
- Heavy-duty steel construction built to handle high hydraulic pressures
- Direct replacement for worn or damaged tube nuts in your hydraulic system
- Compatible with standard hydraulic tubing and O-ring seal systems
Built for Real Farm Work
This tube nut is designed for the hydraulic systems found on tractors, combines, balers, and other farm equipment. Whether you’re dealing with loader circuits, three-point hitch hydraulics, or implement connections, this fitting helps maintain the pressure and flow your equipment needs to operate efficiently.
Made to Last
Steel construction means this tube nut can handle the vibration, temperature changes, and high pressures that come with agricultural hydraulic systems. The precision threading ensures a proper seal with O-ring face seal fittings, giving you confidence that your repair will hold up season after season.
Good to Know
Make sure to use the correct O-ring when installing this tube nut—the seal depends on it. Clean both the tube end and fitting threads before assembly, and tighten to the manufacturer’s torque specification to avoid over-tightening. Keep a few of these on hand since hydraulic fittings tend to wear out over time, especially in high-cycle applications.
