Hydraulic Adaptor, 3/8"MB X 3/8"FP

Hydraulic Adaptor, 3/8"MB X 3/8"FP

The 6405X0606 Hydraulic Adapter is a heavy-duty straight hydraulic fitting designed to connect SAE ORB ports to female NPT threaded connections. Built from durable carbon steel, this adapter provides a strong and reliable connection for high-pressure hydraulic systems. The male SAE ORB end seals with an O-ring for leak-resistant performance, while the female NPT end allows connection to tapered pipe thread fittings or components. With a 5000 PSI working pressure rating, it’s well suited for demanding hydraulic equipment where dependable connections are essential—because in hydraulic systems, even the smallest leak tends to make the biggest mess.
