Hydraulic Adaptor, 1/4"MB X 1/4"FPX

Hydraulic Adaptor, 1/4"MB X 1/4"FPX

The 6900X0404 Hydraulic Adaptor 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 1/4" Male SAE (#4 ORB) connection and a 1/4" Female NPT swivel, this adaptor provides a secure, leak-resistant transition between hydraulic components. Constructed from durable carbon steel and rated for working pressures up to 5000 PSI, it’s built to handle demanding fluid power applications—because when hydraulic pressure is involved, reliable fittings are not optional.
