Hydraulic Male Adaptor, 1/4"MB X 1/4"MP

Hydraulic Male Adaptor, 1/4"MB X 1/4"MP

The 6401X0404 Hydraulic Male Adapter is a straight hydraulic fitting designed to connect SAE O-ring boss (ORB) ports to NPT threaded connections in high-pressure hydraulic systems. Featuring a SAE #4 (7/16"-20 ORB) male end and a 1/4" male NPT connection, this adapter provides a reliable transition between two common hydraulic thread standards. Constructed from durable carbon steel and rated for pressures up to 5000 PSI, it delivers dependable performance in demanding equipment and fluid power systems—because when hydraulics are involved, the fittings need to be just as tough as the machines they’re serving.
