Our Straight Female JIC x Male DIN hydraulic adapters combine two widely used connection types in hydraulic systems. The DIN side features a 24° tapered throat inside the male threads, which creates a secure seal when a tube nut tightens over the metric threads, compressing a ferrule or cutting ring to hold the tube in place. This style is common in industrial applications and is available in three pressure classes: Extra Light Duty (LL), Light Duty (L), and Heavy Duty (S). On the other side, the JIC connection has a 37° flare seating surface with parallel threads, commonly used in fluid power systems. The seal is made by creating contact between the male flared and female coned seats, forming a reliable mechanical connection. These adapters allow for smooth integration between DIN and JIC systems, making them essential for versatile, high-pressure applications.
