Hydraulic Adaptor, 3/8"MJ X 1/4"MP

Hydraulic Adaptor, 3/8"MJ X 1/4"MP

The 2404X0604 Hydraulic Adaptor (3/8" 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 3/8" male JIC (37° flare) connection provides a dependable metal-to-metal sealing surface, while the 1/4" male NPT side threads into standard pipe ports, allowing smooth transitions between hose and pipe connections. Manufactured from durable carbon steel and rated for working pressures up to 5000 PSI, this adapter provides the strength and reliability required in demanding hydraulic applications.
