- Adjustable size: The air conditioner gasket comes in two sizes, approximately 300 cm and approximately 400 cm, allowing you to tailor the length to your installation. It fits all types of sliding installations (horizontal or vertical) and is compatible with all portable air conditioners or air dryers. - Prevent cooling air from escaping: Made with special TU fabric for insulation and treated with a new heat-insulating bleaching process. The seal blocks cold air loss while reflecting sunlight and heat outside, helping cool the room faster and reducing energy use and costs. - Complete sealing: Delivers a tight, gap-free fit thanks to the material and an expanded firm adhesive strip. It prevents cold air from escaping and keeps insects out, providing reliable protection. - Enhanced detail: Features precise cutting and routing areas for easy adjustment without distortion. A textured area near the outlet prevents the tape from loosening after inserting the air hose, eliminating gaps. Use scenarios: - In a living room with a portable AC and a sliding door or window to maintain cool air and reduce energy waste. - In bedrooms or offices with horizontal or vertical sliding openings, to seal the gap around the exhaust hose. - In rental apartments requiring temporary, reliable sealing compatible with all portable AC units, without damaging surfaces.
