F Din X M Din Reducer Complete

Description & Features

Constructed from steel in a straight configuration, this Adaptall reducer provides a reliable connection between two DIN tube fittings of differing sizes. Side one features a female DIN tube thread at M26 x 1.5 (L18), with a hex width of 24mm and a length of 29mm. Side two is a male DIN tube thread at M18 x 1.5 (L12), measuring 32mm across the hex and 34.5mm in length.

The F Din X M Din Reducer Complete is suited for hydraulic line assemblies where a reduction between an L18 and L12 DIN tube connection is required. The straight geometry keeps the connection compact and inline, and steel construction makes it appropriate for demanding industrial hydraulic environments.

Question by: Larry H on Mar 3, 2026, 1:12 PM

Got an L18 female DIN side on a line and need to step it down to an L12 male connection. This the right part for that?

That's what this reducer is built for. The female side is M26 x 1.5 at L18 and the male side comes out at M18 x 1.5 for L12, so it bridges those two DIN tube sizes inline without any angled geometry to deal with. Steel construction holds up well in industrial hydraulic setups, and the straight profile keeps things compact where space is tight.
