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

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

The 1404X0406 Hydraulic Adaptor (1/4" MNPT x 3/8" FNPT Swivel) is a compact straight adaptor designed to connect smaller NPT pipe threads to larger swivel female ports in hydraulic systems. Built from durable carbon steel and rated for working pressures up to 4000 PSI, this fitting provides a dependable connection between hydraulic components while allowing easier alignment during installation. The female NPT swivel end helps simplify assembly by allowing the fitting to rotate into position without twisting the connected hose or component—because fighting with hydraulic fittings is rarely anyone’s favorite part of the job.
