★This is a waterproof cover that can be used at the point where the refrigerant pipe of the air conditioning unit passes through the building structure.★ Installation is as simple as bonding the sleeve pipe and socket together! Compared to traditional putty filling methods, this product minimizes variations in quality due to the skill level of the installer. Additionally, since the water stop is achieved at the adhesive joint between the sleeve pipe and socket, waterproof treatment between the building structure and decorative cover is unnecessary. The waterproof cover is made from tarpaulin material commonly used in tents, making it highly weather-resistant. Furthermore, by filling the gap between the waterproof cover and the refrigerant pipe with the included sealing parts, the intrusion of outside air is minimized, making it less likely for condensation to occur inside the waterproof cover. <Reduced Construction Work> The installation only requires bonding with the sleeve pipe and securing the refrigerant pipe. There is no need for caulking between the piping decorative cover and siding, allowing for a reduction in construction time! <Stable Quality> With less variation in work by the installer, the inspection process can be simplified, and the hassle of corrections due to mistakes can be eliminated! <High Air Tightness> There is no peeling or gaps caused by vibrations or aging, preventing the entry of rainwater and pests! The included sealing parts effectively block the edges of the cover!
