Description
When you’re building custom hydraulic lines or fixing a leak in the middle of harvest, you need fittings that seal tight and stay put. This OFS union tee connects three hydraulic lines at a single point, giving you the flexibility to route hydraulic flow exactly where you need it. Whether you’re plumbing a new loader or adding remote outlets to your system, this fitting handles the job without the headaches.
What You’re Getting
- O-ring Face Seal (OFS) design creates a leak-proof connection that seals on the face, not the threads
- Triple connection point lets you split or combine hydraulic flow in one compact fitting
- Heavy-duty steel construction handles high pressure up to 9,200 PSI without cracking or failing
- Male OFS threads on all three ports make connecting to female OFS fittings simple and secure
- 3/8 inch tube size fits standard hydraulic tubing used throughout agricultural equipment
Built for Real Farm Work
This tee fitting works perfectly for hydraulic systems on tractors, combines, balers, and implements where you need to branch hydraulic flow. Common applications include splitting hydraulic lines for dual remotes, connecting auxiliary circuits, or creating junction points in complex hydraulic systems. The OFS design means you get reliable sealing even when fittings get bumped or vibrated during operation.
Made to Last
Farm hydraulic systems see constant pressure cycling, temperature swings, and plenty of vibration. This steel fitting handles all of that without breaking down. The O-ring face seal design keeps connections tight even when threads get dirty or corroded, something you’ll appreciate when you’re working in muddy conditions or dealing with older equipment.
Good to Know
OFS fittings seal on the O-ring at the face, not on the threads like pipe fittings. This means you don’t need to overtighten them – just snug until the faces contact firmly. Always use the right O-rings for your hydraulic fluid type, and keep a few spare O-rings handy since they’re the wear item in these connections. The 11/16-16 thread size is standard for 3/8 inch OFS applications.
