Dual wall construction means a product is built with an inner wall and an outer wall. In the case of dual wall heat shrink tubing, the space between these layers is filled with a special adhesive lining that activates during heating to create a protective seal.
Dual wall heat shrink tubing is a special type of heat shrink that has two protective layers:
When heat is applied, the inner adhesive melts and flows into small gaps and surface irregularities, forming a strong waterproof and moisture-resistant seal around the cable. This prevents water entry and protects joints from humidity, dust, corrosion, and vibration, making dual wall tubing ideal for automotive, outdoor, underground, and industrial applications. ?
Because of its excellent water-sealing capability and long-term protection, dual wall heat shrink tubing is the preferred choice wherever extra reliability and environmental protection are required.
