XFasten Butyl Tape, Gray, 1/8-Inch x 3/4-Inch x 30-Foot


The XFasten Butyl Tape was formulated and manufactured with the goal of letting average handymen repair their RV and automobile roofing and make it look as if the finished job was done by a pro contractor or repair team.

Wide Operating Temperature Range

We can do this thanks to a -70 to 210 Degree Fahrenheit operating temperature of our tape, something which was certified by the International Organization for Standardization (ISO 9001: Quality).

After installation, you will be left with a seamless, neat and mess free installation. It is certified to be watertight and leak free against water, vapor or corrosive chemicals.

In terms of functionality and aesthetics—the XFasten Rubber Putty Tape can replicate a professional grade finish.

Prevents Unnecessary Melting Into A Messy Puddle of Goo

Thanks to its temperature resistant and anti-corrosion properties, you can easily store the XFasten Butyl Seal Repair Tape in a room with a cool temperature and expect it not to be reduced into a messy puddle of goo that can be hard to handle. It is recommended to store the roll in the fridge at least 6 hours before usage for best results.
