4.8mm down to 1.6mm / Laid flat width = 7.58mm

Semi-flexible, general purpose, adhesive lined, moisture proof heat shrinkable tubing, typically for use when environmentally sealing electrical components, such as wire splices and harness breakouts.

  • High-Strength Bond

  • Perfect Adhesive Tubing

  • Excellent Moisture Proof Seal

  • Excellent Environmental Sealing

4.8mm down to 1.6mm / Laid flat width = 7.58mm

DWA is semi-flexible, heat shrinkable tubing with a meltable adhesive inner lining designed to provide moisture proof sealing to a wide range of substrates such as electrical wire splices, cable jackets, wire breakouts and electrical components.

The high shrink ratios mean that only seven sizes are required to cover a wide range of substrate diameters. Typical applications are environmental sealing of electrical components including wire splices and harness breakouts as well as sealing cable ends against moisture ingress.

Features & Benefits:

  • UL Approved
  • 3:1 shrink ratio
  • High strength bonding
  • Provides excellent environmental sealing
  • Operating temperature range -55°C to +110°C

  • DWA is often used for repairing damaged cables or splicing wires together. 

  • It can also be used in electrical applications to insulate wires and connections

  • The adhesive lining makes it suitable for applications where sealing and waterproofing are a must.

  • It also helps to create a tight seal around the connection, protecting it from moisture and environmental factors

  • Heat shrink tubing is commonly used in automotive applications for wire harnessing, repairing damaged wiring, and protecting connections from moisture and corrosion.

  • DWA can be used to bundle cables and wires together, protecting them from tangling and abrasion, after the heat shrink is shrunk, the adhesive lining helps to keep it in place.
