The hose connector is made of high-quality materials, offering strength and tightness. It features a flat and smooth design, making it durable, safe, and resistant to breaking, while preventing scratches on the installation surface. This professional accessory connects a window sealing plate to an air conditioning exhaust hose with a diameter of 13cm or 15cm. A well-sealed air conditioning hose can help reduce energy consumption. An efficient exhaust ventilation system supports optimal cooling performance and may contribute to lower electricity usage. Available in multiple sizes, this adapter allows you to select the compatible option for your air conditioner hose. Installation is simple: the connector includes a serrated barb at the hose connection point, ensuring a secure fit without damaging the hose. Just insert the hose slowly into the connector for immediate use.
