Guyson can offer various dry-break couplings for critical applications where minimum spillage on disconnection is vital. These include the Mann Tek and Todo ranges (NATO STANAG 3756). Alternatively, the Dry-Link range is also available. In addition, for smaller nb sizes, the Hansen MLDB range is offered.

Applications include handling of chemical, flammable, toxic or other dangerous liquids. Alternatively, they can be used on less aggressive fluids where the environment needs to be free from spillage, such as clean-rooms, laboratories and pharmaceutical process areas. The Mann Tek range also includes safety breakaway couplings and swivel joints.
