Metric Male DIN Heavy Series Hydraulic Fitting

The 4G-8MDH Metric Male DIN Heavy Series Hydraulic Fitting is a MegaCrimp® hose coupling engineered to provide a leak-proof, concentric crimp seal using its patented “C” insert, which helps distribute crimping forces evenly across different hose constructions and wall thicknesses. This design can simplify inventory by allowing one coupling size to accommodate multiple hose ODs on one- and two-wire hoses, while the metric male DIN heavy series connection supports durable hydraulic hookups in demanding systems.
