Sebyahn Portable Air Conditioner Window Vent Kit with 5.9" AC Exhaust Hose Accessorry, Mobile A/C Unit Window Vent Kit with 4 Vent Seal Plates for Vertical/Horizontal Sliding Window — Open-Box, 15% Off

2026 Enhanced Design: A reinforced end support has been integrated into the panel structure to ensure greater installation stability and structural integrity. This feature is optional—panels may be installed directly into the window frame rail where additional support is not required. Seamless Track System: The redesigned continuous slide rail eliminates lateral gaps between adjacent panels. Panels interlock via precision-engineered embedded grooves, ensuring perfect alignment along both edges and smooth integration into the window track. This seamless fit enhances airtightness, improves indoor thermal comfort, reduces cooling load, and contributes to energy efficiency. 5.9-Inch Air Conditioner Exhaust Hose: This AC exhaust hose has a diameter of 5.9 inches and features an anti-clockwise thread direction. It offers excellent telescopic functionality and flexibility, allowing it to be extended up to 59 inches to pass through walls or windows, and retracted to 11 inches for compact storage. Please check the size and thread direction of your old hose before purchasing to ensure compatibility with your AC unit. Premium Thickened PVC Panels: Constructed from high-density, UV-stabilized PVC, the panels offer superior resistance to wear, compression, and thermal deformation. They withstand prolonged exposure to hot exhaust airflow and direct summer sunlight without warping, cracking, or premature aging—ensuring reliable, long-term reusability. Wide-Range Window Compatibility: Designed for universal fit across most vertical and horizontal sliding windows. The kit includes four modular panels with an adjustable span of 17 inches to 63.4 inches (43–161 cm). Users may configure two-, three-, or four-panel assemblies to match their specific window dimensions. (Note: Please measure your sliding window opening length before ordering.) Tool-Free Installation: The vent kit features intuitive, tool-free assembly and disassembly—ideal for residential or office use. Space-efficient design maximizes flexibility without compromising functionality. Includes step-by-step illustrated instructions for rapid setup. Also includes a protective mesh grid to prevent ingress of small animals or debris into the exhaust hose—safeguarding your air conditioner’s internal components.
