+ Free ShippingA practical pick built for real, everyday use — a reinforced end support has been integrated into the panel structure to ensure greater installation stability and structural integrity. It’s available in gray. It weighs 2.6 pounds, comes as 1 count.
- 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.
- Universal 4-in-1 Coupler — This AC window exhaust seal kit comes with a universal 4-in-1 coupler. The inner buckle fits 5.1-inch ventilation hoses (installable in either clockwise or counterclockwise rotation), while the outer buckle is compatible with 5.9-inch exhaust hoses (also supports clockwise or counterclockwise installation). Friendly reminder: Please confirm your exhaust hose size before purchasing.
- 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 54.5 inches (43–138 cm).
