Ss F. Din X M. Din Reducer Complete

Description & Features

Constructed from stainless steel, this straight reducer adapts a female DIN tube connection (M26 x 1.5, L18) to a male DIN tube connection (M18 x 1.5, L12), making it well-suited for hydraulic systems where line size transitions between these two DIN tube sizes are required. The stainless steel construction provides corrosion resistance in demanding fluid power environments.

The Ss F. Din X M. Din Reducer Complete is an Adaptall fitting, with a Ch1 wrench width of 24mm and Ch2 wrench width of 32mm. Overall length runs 29mm on the female side and 34.5mm on the male side. The straight configuration keeps routing straightforward where inline size reduction is needed.

trying to step down from an M26 x 1.5 DIN tube end to M18 x 1.5, is this the right reducer?

Answer by: Customer Support on Aug 11, 2025, 6:43 AM

For a straight inline reduction between those two DIN tube thread callouts, it matches that setup: female DIN tube M26 x 1.5 (size L18) on one side to male DIN tube M18 x 1.5 (size L12) on the other.

what's the thread size on each end of this reducer? trying to figure out if it'll bridge the gap between my existing lines before I go ordering anything

Answer by: Customer Support on Feb 6, 2026, 6:30 AM

The larger female end runs M26 x 1.5 with an L18 tube size, and the smaller male end is M18 x 1.5 with an L12 tube size. Both sides are DIN tube connections, so as long as your existing lines match up to those specs, you're good to go. Overall length comes in at 29mm on the female side and 34.5mm on the male side, which is worth checking against your available space before ordering.

Can this reducer handle a good bit of pressure? I'm using it in a hydraulic setup that sees some spikes.

This reducer is made from stainless steel, so it's built to withstand demanding fluid power environments.
