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

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

The 2404X0606 Hydraulic Adaptor is a straight hydraulic fitting designed to connect JIC flare hose assemblies to NPT threaded ports in hydraulic systems. Featuring a 3/8" Male JIC (37° flare) on one end and a 3/8" Male NPT thread on the other, this adaptor provides a strong, reliable connection between hydraulic hoses and pipe-threaded components. Built from durable carbon steel and rated for working pressures up to 4,000 PSI, it’s well suited for demanding hydraulic applications where dependable sealing and strength are essential—because hydraulic systems tend to notice immediately when a fitting isn’t doing its job.
