Mjic X Male Din 2353S (Sealed)

Yeah, that's exactly what it's built for. One side is a 1-inch JIC male (1-5/16-12 UN thread) and the other is an M30 x 2.0 male DIN tube connection, so it bridges that metric-to-37-degree flare transition in a single straight fitting. No adapters stacked on adapters, just one solid steel piece handling both ends. The sealed DIN 2353S design keeps the connection tight, which matters when you're pulling it into a working system.

This Adaptall fitting is designed to do just that - connect a 1-inch JIC fitting to an M30 X 2.0 DIN tube connection. It's a straight fitting, so it'll give you a direct connection.
