Male Din (Sealed) X Female Npt

On the NPT side, it is a 1-1/4 inch 11.5 NPTF female thread. The other end is a male Metric DIN 2353 S connection, M42 x 2.0 with an S30 DIN tube size, so it is meant to transition from that NPTF female port to a DIN 2353 S male connection.

That's the pairing this adapter handles. One end is a Male M42 x 2.0 DIN 2353 S sealed metric connection, and the other end threads into a 1-1/4 inch 11.5 NPTF female port. Steel construction, straight configuration, so it drops right in without any awkward routing. At 57.5mm long and 50mm across the wrench flats, it fits cleanly into tight hydraulic connections runs without a lot of fuss.

That's correct. It has a Male Metric DIN 2353 S connection (M42 x 2.0) on one side, and a Female NPTF thread (1-1/4 - 11.5) on the other.
