Multi-directional Copper Nozzles Multi-directional copper spray nozzles for ultra-fine misting (x2) Flexible spray nozzles can be directed in any direction Expandable programmable Monsoon misting system Easy to install and maintain The Exo Terra multi-directional copper nozzles allow you to replace your existing nozzles or expand the misting system to multiple terrariums using additional Y-connectors (HAPT2498) and tubing (HAPT2504). The mist produced by these specially designed copper nozzles is ultra-fine, creating a fog effect in your terrarium or greenhouse. Please note that each additional nozzle will reduce the performance of each installed nozzle. We recommend using distilled water.
