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.
