Quick Disconnects

Make aquarium filter maintenance easier with Week Aqua Quick Disconnects. These hose connectors let you separate a section of your filter plumbing when it is time to clean equipment or change the layout. The paired valve design gives you a convenient connection point between the aquarium and external equipment.Choose the variant that matches your hose dimensions. The variant name uses the connection size from the model number; the hose measurements below show the required inner and outer diameters. Quick Disconnect 12/12: QC-1212, for 12/16mm hose on both sides. Quick Disconnect 16/16: QC-1616, for 16/22mm hose on both sides. Quick Disconnect 20/20: QC-2020, for 20/26mm hose on both sides. For a planted aquarium with external CO2 diffusion, explore the Week Aqua CO2 Inline Diffuser and select its hose size separately. Browse NA Aquariums when planning the complete setup.
