Hydraulic Adaptor, 1/2"MB X 3/8"FP

Hydraulic Adaptor, 1/2"MB X 3/8"FP

The 6405X0806 Hydraulic Adaptor is a straight hydraulic fitting designed to connect SAE O-ring boss (ORB) ports to NPT pipe thread components. Featuring a 1/2" male SAE ORB connection and a 3/8" female NPT port, this adaptor allows hydraulic components with different thread standards to be connected securely. Built from durable carbon steel and rated for working pressures up to 4000 PSI, it provides dependable sealing and strength for demanding hydraulic systems—because sometimes the easiest way to connect two different thread types is simply giving them the right adaptor.
