    Heavy Wall Heat Shrink Tubing

    Moodel:WHST

    WHST is recommended to apply for light cable and wire harnesses, where requiring waterproofing, protection of connector components, and thus encapsulates and seals components contained within the tubing.

    Back to list >>

    Heavy Wall Heat Shrink Tubing (WHST) have properties of excellent insulating, environmental sealing, and resistant to 

    impact and abrasion for applications to seal and protect electrical and communication connections, providing excellent 

    mechanical protection to cable joints and terminations,  3:1 shrink ratio allows it easily fit over irregular shape and large 

    connectors. WHST is recommended to apply for light cable and wire harnesses, where requiring waterproofing, protection

    of connector components, and thus encapsulates and seals components contained within the tubing.
