NEED WATERPROOF SEALING?
The adhesive inner liner melts and flows around connectors, creating a fully sealed, watertight joint. Ideal for heat shrink butt connectors, waterproof wire connectors, and marine under-hood applications.
HIGH-VOLUME WORKSHOP USE?
Longer rolls (up to 120 ft), lower cost per foot, UL listed materials. Ideal for electricians, fabricators, and resellers who need reliable insulation without the adhesive liner.
NOT SURE WHICH SIZE FITS?
10 ft rolls let you test fit before investing in bulk. Order multiple sizes for the same cost as a single large roll — then stock up on what works.
