HST Thick Wall Tubing

    Thick Wall Heat Shrink Tubing (HST) is used to dielectrically insulate and encapsulate electrical connections. The HST internal coating has an adhesive and sealant that melts when the tubing is heated to provide a moisture and soil resistant seal. The standard color is black.

    • UL Listed for direct burial. File #E123896.
    • Meets the requirements of the 2023 National Electrical Code: Articles 110.14(B), and 300.5(C)(E).
    • Installs and shrinks easily for labor savings. Most effective when insulating over large transitions.
    • 3:1 Shrink ratios enables wider cable range and fewer tubing sizes.
    • Excellent abrasion, corrosion and environmental resistance properties.
    • UV and fungi resistant.
