Din Union

Description & Features

Manufactured from steel in a straight configuration, this DIN Union provides a male-to-male tube connection in two different DIN sizes within a single compact fitting. Side 1 features an M36 x 2.0 thread at L28 sizing, while Side 2 carries an M30 x 2.0 thread at L22 sizing, making it well suited for hydraulic lines where two differing DIN tube ends must be joined inline.

With an overall L1 length of 36mm, an L2 length of 21mm, and a wrench width of 41mm across the flats, the fitting is dimensionally consistent with standard Adaptall straight union geometry. Steel construction supports use in demanding hydraulic circuits where thread integrity and material durability are required.

Question by: Wade P on Sep 25, 2025, 2:14 PM

got a line with an L28 DIN tube end on one side and L22 on the other. is this the union that ties those together?

Answer by: Customer Support on Sep 27, 2025, 8:53 AM

For joining two different DIN tube sizes inline, this straight steel union is set up exactly for that combo. Side 1 is L28 with an M36 x 2.0 male thread, and Side 2 is L22 with an M30 x 2.0 male thread, so it bridges L28 to L22 in one compact fitting.
