14″ RV A/C Gasket, Ultra-Thick EPDM Seal for Rooftop Units

Ensure the longevity and structural integrity of your recreational vehicle with the EcoSynic Premium RV Air Conditioner Gasket. Specifically engineered for fifth wheels, campers, luxury motorhomes, and units with uneven roof surfaces, this seal addresses the common issue of poor contact between the rooftop unit and the roof deck. The gasket features an upgraded 1.7-inch (4.5 cm) ultra-thick and ultra-soft EPDM construction that compresses easily to accommodate roof irregularities and gaps. This design creates a tighter, more reliable seal, effectively bridging the distance between the air conditioner base and the roof surface to prevent moisture intrusion.

Constructed from premium closed-cell EPDM material, this one-piece seal eliminates the joints and connection points found in segmented alternatives, significantly reducing the risk of water leaks. The high-density composition allows for superior compression recovery, meaning the gasket quickly rebounds after installation and maintains consistent sealing pressure over time. This resistance to flattening and deformation ensures long-lasting performance, even under the rigors of daily use and varying weather conditions.

Installation is streamlined with a self-adhesive backing that holds the gasket securely in place without the need for additional fasteners. The seal provides a dependable airtight and watertight barrier against rain, dust, and outside air, protecting your interior from damage in both freezing and extreme heat environments. With an inner diameter of 14 inches and an outer size of 17 inches by 17 inches, it is a universal fit for standard 14-inch by 14-inch rooftop air conditioner openings, compatible with major brands including Dometic, Coleman, Advent Air, Penguin, and Furrion.
