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 cracking, without scratching the surface of the installation object. This professional accessory connects a window sealing plate to an air conditioning exhaust hose with a diameter of 13cm or 15cm. Effective sealing of the air conditioning hose helps reduce energy consumption, and a well-structured exhaust ventilation system supports efficient cooling performance, potentially lowering electricity usage. Available in multiple sizes, allowing you to select the appropriate air conditioner hose adapter based on your specific requirements. Designed for easy installation, the connector includes a serrated barb at the hose connection point that securely fits the hose without causing damage. Simply insert the hose slowly into the connector for immediate use. Note: - Actual color may vary slightly due to differences in monitor displays and lighting conditions. - Please allow a 1-3cm measurement deviation due to manual measurement.
