Straight Male DIN x Male NPT hydraulic adapters are designed to connect two hydraulic systems that use different thread types. The DIN side of the adapter features a 24° tapered throat inside the male threads, allowing for a secure connection when a tube nut is tightened over the metric threads, compressing a ferrule or cutting ring to grip the tube. The NPT side, which is a U.S. standard for tapered threads, creates a metal-to-metal seal by deforming the threads, ideal for fluid and gas transfer in single-assembly applications. DIN fittings come in three pressure classes—extra light duty, light duty, and heavy duty—making them versatile for various systems. This combination of DIN and NPT ensures compatibility between European and American hydraulic systems while providing a reliable, leak-proof seal.
