The Series 5040S Straight Bulkhead Heavy Duty Male DIN x Male DIN Union hydraulic adapters, made from carbon steel, are designed for high-pressure hydraulic systems where durability and strong, secure connections are essential. These fittings feature a 24° tapered throat angle inside the male threads, which ensures a tight and reliable seal when a tube nut is tightened over the metric threads. This process compresses a ferrule or cutting ring to grip the tube firmly, creating a leak-proof connection. As part of the Heavy Duty (-S) pressure class, these fittings are built to withstand higher pressures and tougher conditions. Additionally, they use the Kobelco fitting style with a 1.5mm thread pitch, making them compatible with a wide range of systems. Ideal for heavy-duty applications, these adapters are perfect for scenarios where reliability and strength are crucial.
