The Series 5000S Straight Heavy Duty Male DIN x Male DIN Union hydraulic adapters, made from carbon steel, are designed for heavy-duty hydraulic systems where high pressure and durability are required. These fittings feature a 24° tapered throat angle inside the male threads, which helps create a secure and reliable connection. The connection is achieved by tightening a tube nut over the metric threads, compressing a ferrule or cutting ring that grips the tube and forms a leak-tight seal. As part of the Heavy Duty (-S) pressure class, these adapters are built to withstand higher pressures and harsh conditions. They also include Kobelco fittings, which use a consistent 1.5mm thread pitch for compatibility and an effective seal in various applications.
