F Din X M Din Reducer

Description & Features

Manufactured from steel in a straight configuration, this Adaptall F Din X M Din Reducer connects a female DIN tube fitting (M24 x 1.5 thread, S16 size) to a male DIN tube fitting (M20 x 1.5 thread, S12 size), providing a reliable step-down connection between two different DIN tube sizes within a hydraulic circuit.

With a Ch1 wrench width of 22mm and Ch2 width of 30mm, the fitting is sized for standard tooling. Overall lengths of 31.5mm (L1) and 36.5mm (L2) keep the assembly compact. The straight body geometry suits inline reducer applications where routing space is limited and a direct port-to-port connection is preferred.

got a female DIN tube end that’s M24 x 1.5 (S16). will this reducer step it down to a male M20 x 1.5 (S12) without any funny business

For a straight step-down between DIN tube sizes, that is exactly what this reducer is built to do. Side 1 is a female DIN tube fitting with M24 x 1.5 threads in S16, and side 2 is a male DIN tube fitting with M20 x 1.5 threads in S12.

got a line running M24 x 1.5 female DIN on one end and need to step down to a M20 x 1.5 male DIN on the other, this the right fitting for that?

Answer by: Customer Support on May 27, 2025, 6:56 AM

That's what this reducer is built for. The female side picks up the M24 x 1.5 thread at S16 size, and the male end connects out at M20 x 1.5 in S12. Straight body, no angle, so it drops right in line between the two ports without any routing complications.
