The Series 5007L Straight Male Light DIN x Male NPT hydraulic adapters are designed to connect hydraulic systems that require both DIN and NPT thread types. The DIN side features a 24° tapered throat inside the male threads, which, when a tube nut is tightened, forces a ferrule or cutting ring to securely grip the tube and form a tight seal. These DIN fittings are classified as light-duty, making them suitable for moderate pressure applications. On the NPT side, the adapter uses a U.S. standard tapered thread, relying on metal-to-metal sealing by thread deformation to provide a leak-proof connection. NPT fittings are ideal for fluid and gas transfer but are best for single-assembly applications, as they are not recommended for frequent disassembly due to thread wear. The combination of these DIN and NPT fittings ensures compatibility and secure connections across a range of hydraulic systems.
