Description
When you’re building or repairing hydraulic lines and need a bulletproof connection between two tubes, this OFS steel union fitting gets the job done right. Those AgSmart fittings are built to handle whatever pressure your hydraulic system can throw at them – up to 5000 PSI – which means they’ll stand up to the demanding work your tractor puts in every day.
What You’re Getting
- Heavy-duty steel construction that handles 5000 PSI working pressure without breaking a sweat
- Male OFS (O-Ring Face Seal) connections on both ends provide leak-free service for years
- Straight-through design keeps hydraulic flow smooth and unrestricted
- 2-1/8 inch hex makes installation and removal easy with standard wrenches
- Direct replacement fitting – no adapters or modifications needed
Built for Real Farm Work
This union fitting connects 1-1/2 inch outside diameter hydraulic tubes in high-pressure applications. Whether you’re running loader circuits on your utility tractor, three-point hydraulics on row crop equipment, or remote hydraulic lines to implements, this fitting handles the constant pressure cycles and vibration that come with real farm work.
Made to Last
Steel construction means this fitting won’t crack or fail like cheaper alternatives. The OFS design uses O-rings in machined grooves to create a positive seal that stays tight even when things get rough. These fittings are engineered to handle the temperature swings and pressure spikes that hydraulic systems see during demanding operations.
Good to Know
Installation requires proper torque on the 2-12 threads – don’t over-tighten and risk damaging the O-ring seats. Make sure your tube ends are cut square and deburred for the best seal. Keep spare O-rings on hand since they’re the wear items in these fittings. A little hydraulic fluid on the threads during assembly makes installation easier and prevents galling.
