Hydraulic Male Adaptor, 5/8"MJ X 5/8"MB

Hydraulic Male Adaptor, 5/8"MJ X 5/8"MB

The 6400X1010 Hydraulic Male Adapter (5/8" MJ x 5/8" MB) is a straight hydraulic fitting designed to connect a 5/8" JIC 37° flare hose end to a 5/8" SAE O-Ring Boss (ORB) port in high-pressure hydraulic systems. Built from durable carbon steel and rated for working pressures up to 3500 PSI, this adapter provides dependable sealing and strength for demanding hydraulic applications. The JIC flare connection delivers a reliable metal-to-metal seal, while the ORB connection uses an O-ring to provide a secure, leak-resistant port seal. It’s a simple, hardworking fitting designed to keep hydraulic systems connected and operating smoothly—because leaks and downtime rarely fit into the day’s schedule.
