Stop leaks before they start. The Camco 25071 is a universal-fit replacement gasket designed for rooftop RV air conditioners. Whether you are swapping out a worn, cracked, or compressed gasket or installing a brand-new AC unit, this kit gives you a reliable compression seal -- no liquid sealant, no silicone, no mess.
The gasket between your rooftop air conditioner and the roof is one of the most overlooked maintenance items on any RV. Over time, UV exposure, temperature cycling, and the constant vibration of travel compress and harden the original foam seal until it no longer keeps a tight barrier. Water intrusion follows -- and water in your roof structure is expensive.
Camco's part 25071 (vendor part CMC25071) solves this with a pre-cut, self-adhesive picture-frame gasket and two foam leveling pads. The kit is sized to the industry-standard 14 x 14 inch rooftop opening used on most Coleman Mach, Dometic, and compatible rooftop units, making it a genuine universal replacement.
Matches the standard 14 x 14 in. interior opening found on the majority of RV rooftop AC units, including Coleman Mach and Dometic compatible models.
Both the picture-frame gasket and the leveling pads include a peel-and-stick backing, so positioning is clean and no additional adhesive is required.
Two thicknesses of foam leveling pad are included -- 7/8 in. and 5/16 in. -- so you can compensate for minor roof camber or uneven mounting surfaces.
The gasket is engineered to seal by compression. Do not apply silicone, tube sealant, or any liquid sealant alongside it; doing so can prevent proper compression and void the seal.
The Camco 25071 kit contains everything needed for a clean replacement install:
The entire kit weighs approximately 0.71 lbs., so it adds negligible load to the rooftop assembly.
Replacing an RV rooftop AC gasket is a manageable DIY job for most RV owners. General steps include:
Inspect the AC roof gasket at least once per season. Signs that replacement is due include:
This gasket is designed around the 14 x 14 in. roof opening that has been the industry standard for RV rooftop air conditioners for decades. It is broadly compatible with:
Always measure your existing roof opening before ordering. If your opening differs from 14 x 14 in., this gasket will not fit correctly.
