The Series 5040L Straight Bulkhead Light Duty Male DIN x Male DIN Union hydraulic adapters, made from stainless steel, are designed for hydraulic systems that need reliable, secure connections, especially in situations where space is limited. These fittings feature a 24° tapered throat angle inside the male threads, which ensures a tight seal when a tube nut is tightened over the metric threads. This tightening action compresses a ferrule or cutting ring that grips the tube, creating a leak-proof connection. As part of the Light Duty (-L) pressure class, these fittings are ideal for lower-pressure applications where ease of installation and space-saving design are important. Additionally, these adapters use the Kobelco fitting style with a 1.5mm thread pitch, making them versatile and compatible with various systems.
