Raklok Couplings A-A-59326 / DIN14420-7

The Raklok couplings are a-symmetrical and manufactured worldwide according to the norms A-A-59326 / DIN14420-7.

The accessories like handles, pins, rings and gaskets are not standardized.

Rakloks according to this norm are used to make a connection between hoses and/ or pipes, also from a fixed point of an installation to a tank-truck to transport liquids, solids and gases, except liquid gas and steam.

The connection is produced when you put the adapter into the coupler and push the handles of the coupler down. This is how you get a good connection in a moment.
