Hydraulic Adapter, 1/2"FS X 3/8"MB

Hydraulic Adapter, 1/2"FS X 3/8"MB

The FS6400X0806 Hydraulic Adapter is a high-pressure straight hydraulic fitting designed to connect 1/2" ORFS (O-Ring Face Seal) systems to 3/8" SAE ORB threaded ports. Constructed from durable carbon steel, this adapter provides a reliable, leak-resistant connection in demanding hydraulic systems. The male ORFS connection on one end and male SAE thread on the other allow efficient transitions between different hydraulic fitting standards, while a 5000 PSI working pressure rating ensures dependable performance in heavy-duty equipment and hydraulic circuits. In short, it’s the kind of adapter that keeps hydraulic systems flowing smoothly instead of turning small leaks into big headaches.
