Hydraulic Union Adaptor, 3/4"MJ X 1/2"MJ

Hydraulic Union Adaptor, 3/4"MJ X 1/2"MJ

The 2403X1208 Hydraulic Union Adaptor is a straight hydraulic fitting designed to connect two different Male JIC thread sizes while maintaining a secure, leak-resistant connection. Built from durable carbon steel and rated for working pressures up to 3500 PSI, this adaptor links 3/4" Male JIC (JIC 12) to 1/2" Male JIC (JIC 8) using the dependable 37° flare sealing system. The straight-through design allows smooth hydraulic flow with minimal restriction, making it a practical solution when adapting between hose sizes in high-pressure systems. In other words, it’s the hydraulic equivalent of a handshake between two fittings that don’t quite match—but now get along perfectly.
