DIN 11851 Union
DIN Union (DIN Male Part, DIN Liner, Din Nut, DIN Gasket)
The DIN 11851 Union (Deutsches Institut für Normung) is comprised of a DIN round slotted nut, DIN male part, DIN liner, and a DIN gasket. DIN blanks and blank nuts with chain are also available.
The easiest way to identify a DIN Union is its D Shape Gasket.
The round thread and the huge tolerances ensure that the coupling always closes.
The DIN coupling is officially standardized with DN dimensions, but there are also types available with inches and ISO dimensions. While it is less commonly used in the local sanitary industries, a lot of equipment or instruments are provided with a coupling DIN 11851.
