Ancor Adhesive Lined Heat Shrink Tubing (ALT) - 3/16" x 48" - 1-Pack - Black

Ancor Adhesive Lined Heat Shrink Tubing (ALT) in 3/16" x 48" – 1-Pack – Black is a professional-grade electrical insulation and protection solution trusted by law enforcement, military personnel, and experienced technicians for mission-critical wiring applications. Whether securing communications equipment, reinforcing connector joints, or waterproofing exposed wire runs in tactical environments, this heat shrink tubing delivers reliable performance under demanding field conditions. The adhesive-lined design eliminates the need for sealant compounds, streamlining installation and reducing maintenance requirements in the field.

Built from cross-linked polyolefin, this tubing offers superior durability and chemical resistance compared to standard heat shrink products, making it ideal for harsh tactical environments—high humidity, fuel exposure, salt spray, and temperature extremes. The 3/16" (4.8mm) diameter shrinks down to 1/16" (1.6mm) when heated, providing a tight, seamless seal over wire bundles in the 20–12 AWG range. The integrated hot-melt adhesive melts during shrinking and cools to form a permanent, waterproof bond that prevents moisture ingress and corrosion—critical for maintaining electrical integrity in field operations where equipment failure is not an option.

This single 48-inch section suits technicians assembling battery harnesses, securing multi-pin connectors, or protecting soldered joints on comms headsets and tactical electronics. Installation is straightforward: slide the tubing over the wire or connector, apply heat using a heat gun or lighter, and allow to cool—the adhesive flows outward to seal gaps and create a moisture barrier.
