Hydraulic Male Adaptor, 1/2"MJ X 5/8"MB

Hydraulic Male Adaptor, 1/2"MJ X 5/8"MB

The 6400X0810 Hydraulic Male Adapter is a straight hydraulic fitting designed to connect a 1/2" Male JIC (37° flare) fitting to a 5/8" Male SAE O-Ring Boss (ORB) port. Constructed from durable carbon steel and rated for working pressures up to 3500 PSI, this adapter provides a dependable connection between JIC hose fittings and SAE straight-thread ports. The 37° JIC flare creates a secure metal-to-metal seal, while the ORB connection uses an O-ring to provide leak-resistant sealing under pressure and vibration. In short, it’s the kind of adapter that quietly keeps hydraulic systems cooperating—so the oil flows where it should instead of decorating the shop floor.
