drybreak

A drybreak is a type of quick-connect coupling designed to minimize or eliminate fluid spillage when disconnecting. It consists of two halves, typically a plug and a socket, which are engineered to automatically seal when separated. When connected, the drybreak allows for the flow of fluid. Upon disconnection, internal valves within each half close simultaneously, preventing the escape of any remaining liquid or gas.

This mechanism is particularly useful in applications where containment of the fluid is critical, such as in the transfer of hazardous chemicals, fuels, or valuable liquids. The absence of spillage not only enhances safety by reducing exposure risks and fire hazards but also contributes to environmental protection by preventing pollution. Drybreaks are also employed to maintain a clean working environment and to prevent contamination of the fluid being transferred.

The design of drybreaks varies, but they generally feature robust materials to withstand pressure and chemical compatibility. They are commonly found in industrial settings, including petrochemical plants, pharmaceutical manufacturing, and in specialized applications like refueling systems for aircraft or spacecraft. The ease of connection and disconnection, coupled with the spill-free operation, makes drybreaks a favored choice for efficient and safe fluid handling.
