Hydraulic Male Adaptor, 1/4"MJ X 1/2"MB

Hydraulic Male Adaptor, 1/4"MJ X 1/2"MB

The 6400X0408 Hydraulic Male Adapter is a straight hydraulic fitting designed to connect JIC hose ends to SAE ORB ports in high-pressure hydraulic systems. Constructed from durable carbon steel, this adapter provides a strong and reliable transition between two common hydraulic connection standards. The male JIC 37° flare on one end and male SAE ORB thread on the other create a secure, leak-resistant connection. With a 5000 PSI working pressure rating, it’s built for demanding hydraulic applications where reliability matters—because in hydraulics, even a small fitting plays a big role in keeping the system running smoothly.
