Camco 14-Inch x 14-Inch Camper Roof A/C Gasket Kit
Features a three-piece kit that includes a self-adhesive picture frame gasket and two self-adhesive leveling pads. The leveling pads come in two thicknesses to accommodate different A/C units, promoting proper alignment. The waterproof compression seal helps prevent leaks around seams and irregularities. Best for: RV owners replacing a single 14″ x 14″ gasket or upgrading to a more robust seal on standard roof openings. Limitation: the kit’s sizing is fixed to 14″ x 14″ openings, so non-standard openings may require alternative options.

Best for a durable, long-lasting seal with clean removal. This gasket uses high-density closed-cell EPDM foam to maintain compression and block moisture, dust, and outdoor air. It fits most standard 14″ x 14″ openings and serves as a direct replacement for worn gaskets. Best for: travelers who want a reliable upgrade that resists weathering and remains easy to remove during replacement. Caution: ensure a proper cleanup of the roof before installation to maximize adhesion and seal effectiveness.
Beeplove One-piece Seamless RV Roof Air Conditioner Gasket Kit
Best for insulation-focused installs. This kit uses EVA foam with waterproofing and includes two leveling pads. The self-adhesive design supports easier installation and helps seal around seams and irregularities. Best for: RV owners prioritizing energy efficiency and a stable, well-insulated roof seal. Limitation: adhesive performance may vary with temperatures; ensure the roof surface is clean and dry before applying.

Best for budget-conscious buyers needing a flexible, adjustable solution. This package includes two complete gasket sets with picture frame gaskets and leveling pads in white and black. The kit’s design allows cutting with scissors to fit various RV models. Best for: those who want cost-effective redundancy or multiple units. Caution: cutting can introduce edge fraying; handle carefully to preserve seal integrity.

Best for straightforward replacement with an adhesive-backed sponge gasket and included leveling block. This option provides an easy, secure install for standard 14″ x 14″ openings.

Buying Guide
What opening size do I need?
Most RV roof air conditioners use a standard 14″ x 14″ opening. Confirm your unit’s opening before selecting a gasket. If your unit isn’t standard, look for universal or adjustable gaskets that can be cut to fit.
Which material lasts longest in varied weather?
EPDM foam and EVA foam tend to resist moisture and UV exposure well. Closed-cell EPDM foam (as used in several Convivium gaskets) tends to hold its shape and seal longer under temperature fluctuations. EVA-based products offer good insulation and flexibility but check adhesive compatibility with your roof surface.
Adhesive backing: permanent vs. removable
Self-adhesive backings simplify installation but performance depends on roof cleanliness and climate. For temporary or frequent replacements, consider gaskets with clean removal capabilities to avoid residue or roof damage.
Do I need leveling pads with my gasket?
Leveling pads help distribute pressure and align the A/C unit for an even seal. Some kits include separate leveling pads; others integrate them or rely on an adjustable frame. Choose a kit that provides leveling pads if your installation requires precise alignment.
How important is waterproof sealing?
A gasket should prevent rain ingress at seams, corners, and irregularities. Look for a gasket described as water-resistant or waterproof and verify that the seal can maintain compression over time with highway vibrations and weather exposure.
FAQ
- What size gasket fits most RV air conditioners? Most standard RV roof air conditioners use a 14″ x 14″ opening, so 14×14 gaskets are widely compatible.
- Are self-adhesive gaskets easy to remove later? Some are designed for clean removal with minimal residue, but check product details if you anticipate frequent replacements.
- Do all gaskets include leveling pads? Not all do; several include leveling pads, while others require separate purchases for leveling aids.
- Can I install a gasket over an old seal? It’s generally best to remove the old seal to ensure a fresh, secure bond for the new gasket.
- Should I use sealing caulk with a gasket? In most cases you should rely on the gasket alone for sealing; avoid over-application of extra sealants that could interfere with adhesion.
- What’s the best gasket for insulation? Gaskets with high-density closed-cell EPDM or EVA foam tend to provide better insulation against temperature changes.
