Our versatile and reliable RV Sealant Tape is a high-performance solution for repairing and sealing leaks in various applications. This butyl rubber caulk tape simplifies the process, offering exceptional convenience compared to messy caulk or tube marine and RV sealants. It is perfect for sealing RV windows, roofs, water heaters, boat port holes, and more.

The 1/8" thick by 3/4" wide sticky putty butyl tape provides extra-strong water resistance, effectively sealing irregular gaps and cracks to create a robust vapor barrier. With a continuous gap-free 36-foot roll supported by paper backing, you can easily seal awkward and unusual shapes. Available in Black, White, or Gray, our tape adheres to a wide range of surfaces.

As a family-owned American business dedicated to producing premium quality boat care and marine grade accessories, we take pride in our products and stand behind your satisfaction. Choose Better Boat for all your boat care needs.
