Din Union

Description & Features

Manufactured from steel in a straight configuration, this Adaptall Din Union provides a reducer-style tube-to-tube connection between two DIN tube ends of differing sizes. Side one carries an M18 x 1.5 male thread at an L12 tube size, while side two steps down to an M16 x 1.5 male thread at an L10 tube size, making it well suited for hydraulic circuits where tube line sizes transition within the same assembly.

At 28mm in overall length with a 19mm across-flats wrench width, the fitting is compact and straightforward to install using standard tooling. As part of the Adaptall range, it is designed for consistent dimensional accuracy and compatibility with standard DIN tube fittings used throughout industrial hydraulic systems.

Will this here fitting work to connect different size lines?

Answer by: Customer Support on Sep 2, 2025, 6:13 AM

Yes, this DIN union adapts between an M18 x 1.5 male thread at an L12 tube size down to an M16 x 1.5 male thread at an L10 tube size.

Got an L12 line feeding into an L10 section on a machine I'm working on, this union the right piece to tie those two together?

Answer by: Customer Support on Jan 2, 2026, 6:30 PM

That's exactly what this fitting is built for. Side one runs M18 x 1.5 male thread at L12, and side two steps down to M16 x 1.5 male thread at L10, so it bridges those two DIN tube sizes in a single straight union. Steel construction, 28mm overall length, and a 19mm wrench flat means it goes in clean with standard tooling and doesn't take up much space in the line.
