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

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

The 6404X0608 Hydraulic Adaptor is a straight hydraulic fitting designed to connect a 3/8" SAE female O-ring boss (ORB) port to a 1/2" male NPT pipe thread, allowing smooth transitions between hydraulic components and pipe-thread systems. Constructed from durable carbon steel and rated for up to 3,000 PSI, this adaptor provides dependable strength and a secure, leak-resistant seal in demanding hydraulic environments. It’s a practical solution when adapting equipment ports to standard pipe connections—because the right adaptor keeps fluid moving instead of turning installation into a guessing game.
