    About Heat-Shrink Tubing
    industrial info icon

    Find tubing with the right shrink ratio, flexibility, and dielectric strength. Plus, compare materials by chemical resistance temperature, and more.

    Wraparound Heat-Shrink Tubing

    Protect wire and cable without disconnecting them from an assembly. This tubing is ideal for adding protection to damaged components that are hard to rewire. For a water-resistant seal, it has an adhesive lining that melts when heated to bond the tubing to the underlying surface. It meets ASTM requirements for flame retardance.
    Adhesive-Strip Closure

    Tubing with an adhesive-strip closure is easy to install. Simply peel off the paper backing, wrap the tubing around your components, seal the adhesive strip, and shrink it. Use this tubing to protect smaller components or bundles of wiring. It meets military specifications for material quality and color.
    ID Before Shrinking—ID Before Shrinking is a minimum value and may be larger than published.
    Dielectric Strength—Dielectric strength is the maximum voltage a material can handle before it starts to breakdown. The higher the dielectric strength of a material, the better it is for preventing electricity, heat, or signal from dissipating from wire and cable.

    Locking-Channel Closure

    Tubing with a locking-channel closure gives you more secure protection than tubing with an adhesive-strip closure. It’s ideal for protecting larger components in applications that demand a strong seal, such as industrial construction and automation systems. To install, wrap the tubing around your components and insert the stainless steel locking channel to hold the tubing together. Then shrink the tubing from the center to the ends. After shrinking, you can leave the locking channel on or remove it, depending on your application.
