Ss F. Din X M. Din Reducer Complete

Description & Features

Constructed from stainless steel, this straight reducing adapter connects a female DIN tube fitting (M22 x 1.5 thread, L15 size) on one end to a male DIN tube fitting (M18 x 1.5 thread, L12 size) on the other. The Ss F. Din X M. Din Reducer Complete is manufactured by Adaptall and is suited for hydraulic line assemblies where a reduction between two DIN-standard tube connections is required.

With an overall length of 35.5mm and a female-side length of 29.5mm, the adapter is compact enough for space-limited installations. Wrench flats measure 22mm on the female side and 27mm on the male side, supporting secure assembly with standard tooling. Stainless steel construction makes this fitting appropriate for applications where corrosion resistance is a priority.

Question by: Hubert C on Dec 30, 2025, 3:35 PM

What exactly is this fitting doing in a hydraulic line, is it just stepping down tube sizes between two DIN connections?

Answer by: Customer Support on Jan 1, 2026, 6:41 AM

That's exactly what it's for. One end is a female DIN tube fitting at M22 x 1.5 with an L15 size, and the other end is a male DIN tube fitting at M18 x 1.5 with an L12 size. So wherever you've got a larger DIN connection feeding into a smaller one, this adapter bridges that gap in a straight run without needing extra fittings or fabrication.

Hey, will this here reducer work alright with stainless steel hydraulic lines?

Answer by: Customer Support on Sep 28, 2025, 8:05 PM

Seeing as it's made from stainless steel, this reducer should be compatible with other stainless lines and hold up well in systems where corrosion might be a concern.

got a hose end that’s M22 x 1.5 on a DIN L15, and the other side needs to be M18 x 1.5 L12. is this the right reducer?

Answer by: Customer Support on Feb 12, 2026, 9:25 PM

Straight reduction is exactly what this adapter is built for. One end is a female DIN tube fitting M22 x 1.5 in L15, and the other end is a male DIN tube fitting M18 x 1.5 in L12.
