A Straight Female DIN Swivel x Male Metric Hydraulic Adapter is a versatile fitting used to connect hydraulic systems with different types of threads. The female end of this adapter is designed with a DIN swivel connection, which has a 24° tapered throat angle for a secure, leak-proof seal. The male end features a metric thread, commonly used in European hydraulic systems, with an outer diameter measurement in millimeters, followed by the thread pitch. For example, an M22x1.5 fitting would have a 22mm outer diameter and a 1.5mm thread pitch. This adapter allows for efficient and secure tube connections by tightening a tube nut over the metric threads, which compresses a ferrule or cutting ring to hold the assembly in place and create a seal. The adapter is ideal for various pressure classes—extra light duty, light duty, or heavy duty—ensuring a reliable and durable hydraulic connection.
