Din Union

Description & Features

Manufactured from steel in a straight configuration, this Adaptall Din Union provides a reducer-style connection between two DIN tube ends in male-to-male orientation. Side 1 features an M22 x 1.5 male DIN tube fitting sized at L15, while Side 2 steps down to an M18 x 1.5 male DIN tube fitting at L12, making it suited for hydraulic lines where a transition between these two metric DIN sizes is required.

With an overall L1 length of 29mm, an L2 length of 15mm, and a wrench width of 24mm across flats, the fitting is compact and compatible with standard tooling. Steel construction supports use in demanding hydraulic service environments where durability and thread integrity are priorities.

This union needs a 24mm wrench for tightening.

Got a hydraulic line running M22 x 1.5 on one end and need to drop down to M18 x 1.5 on the other, this the right piece for that?

Answer by: Customer Support on Jan 5, 2026, 8:52 PM

That's exactly what this fitting handles. Side 1 is M22 x 1.5 male DIN at L15, and Side 2 steps down to M18 x 1.5 male DIN at L12, so it bridges those two metric sizes in a straight, male-to-male configuration. Both ends are DIN tube type, so as long as your line ends match those specs, you're in good shape.
