Ss Din Union

Ask A Question

Description & Features

Constructed from stainless steel, this straight union provides a male-to-male DIN tube connection on both ends, making it well suited for hydraulic line assemblies where corrosion resistance and a secure, leak-free joint are required. Both sides carry an M20 x 1.5 thread with an S12 size designation, and the fitting measures 34mm in overall length with a 19mm L2 length and a 22mm wrench width across the flats.

The Ss Din Union is an Adaptall product, designed to mate DIN tube ends in a straight-through configuration. Stainless steel construction supports use in demanding environments where carbon steel fittings would be unsuitable, including washdown areas and applications involving aggressive media or elevated ambient moisture.

Question by: Billy G on Jul 7, 2025, 5:37 PM
both ends are M20 x 1.5 DIN tube, right? just want to make sure this ain't one of those fittings where one side's different
Answer by: Customer Support on Jul 9, 2025, 6:18 AM
Correct on both counts. Each side is an M20 x 1.5 male DIN tube connection, S12 size, so you're getting a true straight-through union with matching ends. No mixed thread or size surprises here.

got a DIN tube setup with S12 ends, is this union the straight male to male piece or am i lookin at the wrong thing
Answer by: Customer Support on Mar 7, 2026, 11:00 AM
Built as a straight-through DIN tube union, it connects DIN tube ends with male threads on both sides. Both ends are M20 x 1.5 with the S12 size, so it is a male-to-male DIN tube connection.
