Description: Internal half Beswick series QB dry break quick disconnect assembly. The dry break quick disconnect functions similar to a double shut-off quick disconnect however it provides a higher level of sealing during connection and disconnection. The dry break connects without leakage or fluid spray. Additionally, the design minimizes dead volume (the space between the internal and external ends when connected) to essentially eliminate any leakage when disconnecting.

Max Pressure Rating: 500 psig while connected.  200 psig while connecting or disconnecting.*

*Note that the pressure rating of configurations using barbs will likely be limited by tubing selection.

Materials: 303 or 316 stainless steel body. ENP brass nut, 410 stainless steel washers included with panel mount configurations.

Maximum Spill Volume Upon Disconnection: Approximately 0.2 mL
