Replacement and custom-panel connection parts for standard dual-hose portable air conditioners.

This collection includes the four main pieces used in the dual-hose window connection system: the left connector half, right connector half, replacement hose plate and air separator.

The left and right connector halves join together to create the window-panel connector. The AC’s oval hose plate locks into that connector, while the air separator helps keep hot exhaust airflow separated from fresh intake airflow.

These parts are useful for two common situations: replacing damaged or missing pieces from an existing dual-hose setup, or building a custom acrylic window panel where the connector is mounted into the panel instead of locking the hose plate directly into the acrylic.

Factory dual-hose window kits are typically set up for horizontal sliding windows. Using the assembled connector allows the oval connection to be positioned vertically, making it practical for vertical sliding windows, casement windows and other custom window-panel applications.

Each product listing identifies exactly which component is included. Individual replacement parts are sold separately.
