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

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

The 2404X0404 Hydraulic Adaptor (1/4" MJ × 1/4" MP) is a straight hydraulic fitting designed to connect JIC hose assemblies to NPT pipe-thread ports in high-pressure hydraulic systems. The 1/4" male JIC (37° flare) connection provides a reliable metal-to-metal seal, while the 1/4" male NPT side threads into standard pipe ports, allowing a secure transition between hose and pipe-thread connections. Manufactured from durable carbon steel and rated for working pressures up to 5000 PSI, this adapter is built to perform reliably in demanding hydraulic applications.
