Convivium RV AC Gasket 14x14 — Self-Adhesive Closed-Cell EPDM Leak-Proof Roof Seal, Easy Install

Convivium's 14" x 14" self-adhesive closed-cell EPDM foam gasket provides a durable, leak-resistant seal for standard rooftop RV air conditioners.

Replace a cracked or failing factory gasket with a long-lasting, easy-to-install foam seal designed for 14" x 14" AC openings found on most travel trailers, fifth wheels and motorhomes. This gasket is made from high-density closed-cell EPDM rubber that keeps rain, dust and drafts out while maintaining compression under the AC unit. The peel-and-stick backing adheres firmly during travel yet removes cleanly when it’s time for another replacement.

How will this gasket stop leaks in wet weather?

The closed-cell EPDM foam resists water absorption and holds its shape under compression, creating a continuous barrier around the AC flange. Its dense structure and snug fit keep water from seeping between the unit and the roof, reducing the chance of roof damage or interior leaks.

• High-density closed-cell EPDM prevents water wicking.
• Compresses to form a tight waterproof interface under the AC.
• Self-adhesive backing reduces gaps during installation.
• Designed for standard 14" x 14" rooftop AC openings.

Is installation difficult for a DIY camper owner?

Installation is straightforward and requires no special tools: remove the old gasket, clean the roof surface, peel the liner, and press the gasket into place before reinstalling the AC. Most RV owners can complete the swap in under an hour, and the adhesive holds securely through highway vibration and weather.

• Peel-and-stick application—no separate sealant needed in most cases.
• Works with standard mounting bolts; avoid over-tightening.
• Removes cleanly when replacement is necessary.
• Clear installation steps suitable for first-time DIYers.

Will this gasket fit my RV air conditioner and stay durable over time?

It’s made to fit standard 14" x 14" AC openings used by many rooftop units, making it a universal replacement option for a wide range of RVs. The EPDM formulation resists UV, ozone and temperature cycling to retain sealing performance across seasons, while the adhesive backing is formulated to withstand vibration and road conditions.

• Universal 14" x 14" sizing for most rooftop AC units.
• EPDM resists UV degradation and thermal expansion.
• Strong adhesive withstands travel-related movement.
• Recommended for repair, replacement, or seal upgrades.
