Made from high-density foam with a self-adhesive backing, it ensures easy installation and a secure fit. The gasket features an inner size of 11" x 14" and an outer size of 14" x 17", ideal replacement for worn-out AC gaskets. DIY RV Air Conditioner Foam Block Kit: The gasket pad/strip can be customized as foam block kits. The foam block kit is for use on installations where the vehicle roof surface is extremely smooth and with normal unit gasket tension and the Air Conditioner may still be able to shift position; helps to keep tension on the unit mounting bolts. Leak Fix Foam Strip & Gap Filling Foam Tape: The gasket pad/strip can be designed to adapt to uneven roof surfaces, the A/C roof gasket strip is designed to seal small gaps around your RV air conditioner, helping prevent water leaks and air loss. The foam pad can be easily cut into different sizes and shapes, allowing you to customize the thickness and fit based on your specific installation needs. Fixing RV Rooftop Vibration Issues: The gasket pad/strip acts as a cushion between the AC unit/solar panel and roof, reducing movement and vibration. The high-density foam gasket not only reduces rooftop vibration but also absorbs road shocks, minimizes AC operational vibration, and prevents structural rattling. DIY RV AC Airflow Divider: The gasket pad/strip can be used together with aluminum foil tape to create a custom air divider, helping separate cold air and return air for improved cooling efficiency.
