DIN Couplings

DIN is a collective term for a group of European hose fittings with the term borrowed from the German Industry Standard (Deutsches Institut für Normung).

This is the officially recognised national-standards body of the German government. DIN is recognised across Europe as the standard German Tanker connection. DIN unions are used in conjunction with German and other European fluid transfer equipment.

There are Three Ranges of DIN Coupling 

  • Storz - German origin – Used in both firefighting and industrial applications
  • Guillimin Symetrique -  French Origin – also mainly used in firefighting and industrial environments
  • Roman Seliger - German Origin - A type of coupling more suited to chemical handling.

How does it Work? 

Typically, these fittings are comprised of two halves which are identical, and connect by twisting the two halves together. 

Applications 

They are ideal for the transfer of liquid that require high flowrates. A common application for the three groups of DIN fittings we supply into is firefighting equipment.
