MannTek Dry Disconnect Coupling (DDC)

MannTek Dry Disconnect Coupling (DDC)

MannTek Dry Disconnect or Drybreak couplings have a large range of applications such as tanker loading, oil and chemical loading, food, pharmaceutical feed stock, or indeed, for any hazardous or critical fluid transfer application. 'MannTek' drybreak couplings provide a proven solution when a drybreak is required.

MannTek couplings are manufactured to the internationally recognised STANAG 3756 standard which ensures compatibility with similar bayonet couplings such as Todo, Avery Hardoll etc...

MannTek couplings comprise of two parts; a hose unit (female part) & a tank unit (male part).

Both parts feature a valve assembly. When the hose and tank unit are mated together using a simple quarter turn, the 2 valves engage & open, allowing product to pass through the coupling.

On disconnection, the valves close independently and hold back any product in the hose or fixed pipeline, therefore offering a 'dry' disconnect.
