Hydraulic Adapter, 3/4"FS X 3/4"MB

Hydraulic Adapter, 3/4"FS X 3/4"MB

The FS6400X1212 Hydraulic Straight Adapter is a durable hydraulic fitting designed to connect 3/4" Male O-Ring Face Seal (ORFS) fittings to 3/4" Male O-Ring Boss (ORB) ports. Built from carbon steel for strength and corrosion resistance, this straight adapter provides secure, leak-resistant connections in hydraulic systems operating up to 3,500 PSI. The ORFS sealing design offers reliable sealing under high pressure, while the ORB connection allows precise positioning in ports commonly found on hydraulic components. Ideal for agricultural, construction, and industrial hydraulic systems where dependable fluid connections are critical—because in hydraulics, a solid connection is the difference between smooth operation and a very oily problem.
