Sold & Installed at California RV Specialists
California RV Specialists proudly sells and installs RV roof air conditioner gaskets, a critical but often overlooked component of your RV’s cooling system. A properly installed AC gasket creates the weather-tight seal between your roof air conditioner and the RV roof opening—helping prevent water leaks, air loss, vibration, and roof damage.
We carry Ventmate® air conditioner gasket kits, a trusted choice of RV dealers since 1995, designed to deliver a long-lasting, watertight seal for common RV roof AC openings.
Why RV Roof Air Conditioner Gaskets Are Important
Your roof air conditioner sits directly over a large roof opening. When the gasket becomes compressed, cracked, or improperly installed, it can lead to serious issues.
How a New AC Gasket Prevents Damage
- Prevents water intrusion around the air conditioner opening
- Reduces risk of roof rot, ceiling damage, and mold
- Maintains proper air seal for efficient cooling
- Minimizes vibration and movement of the rooftop unit
- Helps ensure correct mounting pressure on the roof structure
Replacing an aging or flattened gasket is one of the most important steps when installing, replacing, or servicing an RV roof air conditioner.
