The Series SS5007L Straight Male Light DIN x Male NPT hydraulic adapters, made from durable stainless steel, are designed to connect hydraulic systems using both DIN and NPT thread types. The DIN side features a 24° tapered throat inside the male threads, and when a tube nut is tightened, it compresses a ferrule or cutting ring to create a secure seal. These DIN fittings are classified as light-duty, ideal for moderate pressure applications. On the NPT side, the adapters use a U.S. standard tapered thread, creating a leak-proof seal through metal-to-metal contact. NPT connections are best for fluid and gas transfer, and they provide a permanent connection that is not suited for frequent disassembly. The combination of stainless steel construction and the reliable sealing mechanism ensures strong, secure connections in hydraulic systems across various industries.
