When you’re running hydraulic equipment and need to connect different thread types, having the right adapter can save your day. This steel connector lets you adapt between OFS (O-ring Face Seal) and ORB (O-ring Boss) hydraulic connections—two different sealing methods that don’t play well together without the right fitting. If you’ve ever been stuck trying to connect mismatched hydraulic fittings while your implement sits idle, you know how handy an adapter like this can be.
What You’re Getting
- Converts between 1/4″ Male OFS and 3/8″ Male ORB thread types for versatile hydraulic connections
- Steel construction that handles the pressure and vibration of hydraulic systems without cracking or leaking
- 9,200 PSI operating pressure rating that easily handles most agricultural hydraulic applications
- Compact straight design with 5/8″ hex for easy installation with standard wrenches
- Direct connection—no additional seals or modifications needed
Built for Real Farm Work
This adapter is perfect for connecting hydraulic lines on tractors, loaders, and implements where you need to join different thread standards. Whether you’re retrofitting older equipment with newer hydraulic components, repairing a system with mixed fittings, or adapting aftermarket parts to your existing setup, this connector bridges the gap between incompatible thread types.
Made to Last
Steel construction means this fitting won’t crack under pressure like some lightweight alternatives. The O-ring sealing surfaces are machined to proper specifications for leak-free operation, and the hex flats give you good purchase for proper tightening without rounding off. Built to handle the constant pressure cycles and temperature swings that come with hydraulic work.
Good to Know
Make sure both connections are clean before installing—dirt in hydraulic fittings is a recipe for leaks. Use appropriate thread sealant on the pipe threads but avoid getting any on the O-ring sealing surfaces. Tighten to specification rather than just “as tight as you can get it”—over-tightening can damage the fitting or the components you’re connecting to.
