Metric Male DIN Heavy Series Hydraulic Fitting

The 4G-10MDH Metric Male DIN Heavy Series Hydraulic Fitting is a MegaCrimp® crimp coupling built for DIN Heavy Series metric male hydraulic connections where strength and leak resistance matter. Featuring MegaCrimp®’s patented internal “C” insert, it helps evenly distribute crimping forces to form a concentric, leak-proof seal while accommodating different hose constructions and wall thicknesses—helping simplify inventory across common one- and two-wire hose builds.
