The Series 5315L Straight Female Light Duty DIN Swivel x Male Light Duty DIN Reducer hydraulic adapters are designed to connect two hydraulic systems with different sizes of DIN fittings. These adapters feature a 24° tapered throat angle inside the male threads, providing a secure and tight seal when connected. The tube nut, when tightened, compresses a ferrule or cutting ring around the tube to ensure a leak-free connection. The swivel design allows for flexibility in positioning the connection, while the reducer function ensures a smooth transition between different sizes of tubing. These adapters are part of the DIN system, with a 1.5mm thread pitch, and are classified under Light Duty (L) for lower pressure applications, making them ideal for reliable and efficient fluid transfer in hydraulic systems.
