Din X Male Npt

For tying mixed standards together, this adapter gives you a straight transition from an M16 x 1.5 DIN tube fitting on one end (L10 DIN side) to a 1/2 inch 14 NPTF male thread on the other, so an NPT-threaded component can interface with a DIN tube port.

That's the kind of situation this fitting handles. One end is M16 x 1.5 DIN tube, and the other is 1/2"-14 NPTF male, so you're getting a direct male-to-male connection between those two standards in one compact steel piece. Both sides are machined to standard dimensional tolerances, so sealing under typical hydraulic line pressures shouldn't be an issue. Just make sure your valve block port is female NPT to accept the male NPT end, and your DIN tube fitting on the other side is also female to receive the male DIN end.
