Hydraulic Adapter, 3/8"FS X 3/8"MB

Hydraulic Adapter, 3/8"FS X 3/8"MB

The FS6400X0606 Hydraulic Adapter (3/8" ORFS x 3/8" ORB) is a high-pressure straight hydraulic adapter designed to connect ORFS hose fittings to SAE O-ring boss ports in demanding hydraulic systems. Built from durable carbon steel and rated for working pressures up to 5000 PSI, this fitting provides a secure, leak-resistant connection between hydraulic hoses and equipment ports. The male ORFS (O-Ring Face Seal) end ensures reliable sealing against a flat-face connection, while the male SAE ORB end seals tightly within threaded ports using an O-ring—helping keep hydraulic systems running smoothly without unwanted leaks.
