When you’re putting together hydraulic hose assemblies or replacing worn fittings on your loader or implement, you need connections that won’t leak under pressure. This UNO male O-ring fitting gives you a secure, leak-proof connection for your 3/8 inch hydraulic hose that’ll handle the demands of farm work.
What You’re Getting
- Male UNO thread design with 9/16 inch thread that connects to female O-ring boss ports
- Built-in O-ring seal that prevents leaks even under high hydraulic pressure
- Crimp-on design that creates a permanent, secure connection to your hose
- Quality Ryco construction from their trusted T2000 series hydraulic fittings line
Built for Real Farm Work
This fitting connects 3/8 inch hydraulic hose to equipment ports that use the UNO (Unified National O-ring) thread standard. You’ll find these connections on hydraulic cylinders, valves, and ports throughout your tractor and implement hydraulic systems. Whether you’re running a front loader, operating a three-point hitch implement, or powering remote hydraulics, this fitting handles the pressure and keeps the fluid flowing where it should.
Made to Last
Farm hydraulic systems see high pressures, temperature swings, and constant vibration. This fitting is built to handle those conditions with quality materials and precise manufacturing. The O-ring seal stays flexible and maintains its sealing properties through countless pressure cycles and temperature changes.
Installation Notes
This is a crimp-on fitting that requires proper hydraulic hose crimping equipment to install. Make sure your hose is cut square and clean before crimping, and follow proper crimp diameter specifications for a secure connection. The UNO thread screws into female O-ring boss ports – no pipe thread compound needed since the O-ring does the sealing.
