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

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

The 6404X0808 Hydraulic Straight Adapter connects 1/2 in female SAE O-Ring Boss (ORB) ports to 1/2 in male NPT pipe threads, allowing hydraulic systems to transition between ORB and tapered pipe connections. The straight adapter design keeps flow direct while providing a secure seal between two common hydraulic thread standards. Built from durable carbon steel and rated for working pressures up to 3000 PSI, it’s well suited for agricultural, industrial, and mobile hydraulic systems where reliability matters—because a proper thread conversion is far better than forcing mismatched fittings to cooperate.
