Insulate and protect quickly

Single wall heat shrink tubing insulates, provides strain relief, and protects against mechanical damage and abrasion. Our heat shrink tubing offers a high-performance alternative to standard approaches for insulation, such as taping and molding in place. The tubing comes in a wide range of sizes, colors, and materials. When heated, it shrinks to conform to the size and shape of the underlying material - making installation fast and easy.
