Hydraulic Adaptor, 1/2"FB X 3/8"MP

A dependable straight hydraulic adaptor designed to connect SAE O-Ring Boss ports to NPT threaded hydraulic lines while maintaining a strong, leak-resistant connection. The 6404X0806 hydraulic adaptor features a 1/2" female SAE ORB connection paired with a 3/8" male NPT thread, allowing hydraulic components with different connection styles to work together smoothly. Built from durable carbon steel and rated for working pressures up to 4000 PSI, this fitting delivers reliable performance in demanding hydraulic systems—because the right adaptor keeps the oil flowing where it should instead of slowly decorating the shop floor.
