Butyl tape is an essential tool for weatherproofing marine and RV components. This sturdy material creates a long-lasting, weatherproof gasket to fill gaps between your RV's outer hull and the mounting points for vents, windows, and doors.
Features:
Specs:
Butyl tape is used primarily as a gasket for preventing moisture from leaking into your RV around cutouts in the hull for vents, doors, windows, and wiring outlets. Butyl tape is widely used by RV manufacturers because of its high performance and durability. It does not dry out and crack over time, and its strong adhesive quality means it sticks and stays in place on smooth surfaces.
Butyl tape is most often used in conjunction with sealants to create the highest level of weatherproofing to prevent leaks and ongoing damage. It's ideal for use in areas where fixtures need to be drilled, nailed or bolted into place. The rubbery material keeps those openings sealed and free from water damage. While this is great for those who do their own repairs and upgrades, butyl tape is also good to have on hand to make temporary repairs. The tacky material can plug up any problem areas and hold strong, so you don't have to cut your trip short.

Seal is watertight and secure after a lot of miles of travel.
