Premium Dual-Layer Foam Gasket for Nomadic Rooftop A/C Units

Upgrade your Nomadic A/C installation with our premium dual-layer foam gasket, designed to provide a better seal, reduce noise, and simplify installation. At 1.5" thick, this one-piece gasket can be custom notched to match the contours of your van's roof for a secure, professional fit. Premium Dual-Layer Design: Closed-cell top for sealing, open-cell bottom for sound dampening. One-Piece Form Factor: Easier placement and sealing without awkward wrapping. 1.5" Thickness: Provides ample material for shaping and notching around custom roofs. Self-Adhesive Backing: Installs quickly without tools or fasteners. AC Isolation Barrier: Includes 7" x 3.5" foam pieces for separating hot/cold sides. Perfect Fit for Nomadic AC Units: Designed specifically to elevate your off-grid install. We recommend this upgraded gasket for all Nomadic A/C installations, especially when a thicker seal is needed. Compared to stacking or wrapping thinner gaskets, this one-piece design offers cleaner installation, improved sealing, and less hassle. Note: This upgraded gasket is sold separately and is not included with Nomadic A/C units. We also recommend applying silicone sealant during installation to help achieve a watertight seal.
