It creates more working space for your air conditioning exhaust pipe and provides additional clearance for the pipe to pass through the wall or window frame, helping achieve optimal efficiency. Easy installation: The air conditioning hose connector can be easily screwed into place without professional tools, ensuring a secure fit and helping reduce energy consumption. Wide application: Use our portable AC coupler to expand installation options for your AC unit. It is compatible with both clockwise and counterclockwise exhaust pipes, and offers two pipe sizes to choose from, fitting outer pipes of 15 cm and inner pipes of 13 cm, increasing compatibility and usability.
