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, without scratching the surface of the installation object. This professional accessory connects the window sealing plate and the air-conditioning exhaust hose with a diameter of 13cm or 15cm. A well-sealed air conditioning hose can help reduce energy consumption, and an efficient exhaust ventilation system supports optimal cooling performance, potentially lowering electricity usage. Available in multiple sizes, allowing you to choose the compatible air conditioner hose adapter based on your needs. Features a serrated bar inside the connection port, ensuring a secure fit with the hose without causing damage. Simply insert the hose slowly into the connector for quick and easy installation.
