- Heat insulation and energy saving: This AC pipe cover is made of insulation material to insulate the heat from the exhaust pipe. It helps keep the indoor space cooler, improves the cooling efficiency of the air conditioner, and can reduce electricity costs. The outer cover protects the exhaust pipe from ageing, reduces pipe damage, and extends service life. - New upgraded material: 3 layer insulation featuring acrylic knitted fabric, cotton layer and EVA foam for better insulation. The softer feel makes the pipe sleeve easier to bend without wrinkling during installation, while remaining flexible, foldable, and easy to store. - Universal compatibility and size: 60 inches long and 50 inches wide, designed to fit all brands of exhaust pipes with 5 inches and 5.9 inches diameter within a 60 inch length. If the cover is longer than your pipe, bend the excess length and attach it with the included straps. - Easy installation: Velcro fastener allows efficient, tool-free installation. Includes two adjustable straps for a secure fit. If your hose is attached to the air conditioner, it is better to remove the hose for installation. - Use scenarios: ideal for home or office window or portable air conditioners to reduce heat loss and protect pipes; suitable for rental properties or multi-unit setups where quick removal and reinstallation are needed; convenient for storage or transport due to its foldable design.
