The Series 5000S Straight Heavy Duty Male DIN x Male DIN Union hydraulic adapters, made from stainless steel, are designed for high-pressure hydraulic systems that require robust and reliable connections. These fittings feature a 24° tapered throat angle inside the male threads, ensuring a tight seal when a tube nut is tightened over the metric threads. This action compresses a ferrule or cutting ring around the tube, securing the connection and preventing leaks. As part of the Heavy Duty (-S) pressure class, these adapters are built to handle intense pressure and challenging conditions. The adapters also incorporate Kobelco fittings, which use a 1.5mm thread pitch for consistent performance and compatibility across all sizes. These fittings are perfect for applications where durability, strength, and leak-free connections are critical.
