*Do NOT buy one of these for your own DIY project*

*These are ONLY for customers who have purchased an acrylic window vent kit*

This is our own proprietary Quick Connect hose adapter. It threads on to the end of your ac hose and locks into your plexiglass window panel with a slight twist. 

Our Quick Connect hose adapter features a stainless steel wire mesh that keeps out the smallest of insects while maintaining optimum airflow. (All non 5.9 hose adapters feature a fabric bug screen).

Features

  • Easily threads on to your ac hose
  • Features a stainless steel wire mesh 
  • 2mm holes keep the smallest insects out and maintain optimal airflow

Compatibility

Fits 95% of all ac units.

*Most ac units have a 5.9 diameter hose. Measure the diameter of your bare hose before ordering.
