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

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

The 2403X0404 Hydraulic Union Adaptor (1/4" MJ × 1/4" MJ) is a straight hydraulic union designed to connect two JIC hose fittings together in high-pressure hydraulic systems. Both ends feature 1/4" male JIC (37° flare) connections, allowing secure metal-to-metal sealing when joining compatible hydraulic hose assemblies or components. Constructed from durable carbon steel and rated for working pressures up to 5000 PSI, this fitting delivers dependable strength and leak-resistant performance in demanding hydraulic environments. It’s a straightforward connector that keeps hydraulic lines working together—because sometimes the simplest fitting is the one that keeps everything flowing smoothly.
