EcoSynic 14” RV AC Gasket Kit – Universal Fit Leak-Proof Seal

Upgrade your RV’s roof-mounted air conditioner with the EcoSynic 14”x14” RV AC Gasket Replacement Kit, designed for a tight, leak-proof seal that keeps moisture and debris out while maintaining proper airflow. This universal-fit kit replaces worn or damaged gaskets on most major brands, including Dometic, Airxcel, Advent, Atwood, and Coleman units, ensuring a secure seal without the hassle of piecing together multiple parts.

The kit features a one-piece closed-cell foam gasket with a durable adhesive backing for easy peel-and-stick installation. Its flexible yet sturdy construction resists compression over time, while the thick and thin gasket strips provide additional sealing reinforcement. Beyond basic replacement, this gasket can be repurposed as a foam block kit to prevent unit shifting on smooth rooftops or as a custom airflow divider when paired with aluminum foil tape—boosting cooling efficiency by separating cold and return air.

Perfect for DIY enthusiasts, this kit requires no specialized tools and adapts to most RV roof surfaces, including trailers and vans. The closed-cell foam material is waterproof, mold-resistant, and long-lasting, making it a reliable upgrade for any RV owner looking to prevent leaks and improve energy efficiency.
