Delock Heat Shrink Tubing Box with Adhesive, 5 m x 25.4 mm, Black

Delock Heat Shrink Tubing with Adhesive – Waterproof Cable Sealing

The Delock heat shrink tubing with adhesive is a heat-shrinkable polyolefin tube that reliably insulates and seals cable connections. The integrated adhesive layer melts when heated, providing a durable, waterproof seal.

• 5 metres length provides enough material for multiple applications in modelling and electrical installations
• 25.4 mm diameter before shrinking – suitable for cable cross-sections up to approx. 12 mm after shrinking
• Inner adhesive penetrates gaps and prevents moisture ingress
• Polyolefin material is flexible and shrinks evenly when heated

What sets the Delock heat shrink tubing apart

Unlike standard heat shrink without adhesive, this model offers an additional sealing layer that is especially important for outdoor or humid environments. The adhesive melts during heating and flows into crevices, preventing any moisture penetration.

Ideal for...

Modellers, electricians and DIY enthusiasts who need to professionally insulate and protect cable connections in RC models, boats, solar systems or outdoor lighting from corrosion.

How to use Delock heat shrink tubing

Slide the heat shrink tube over the cable connection to be insulated and heat it evenly with a hot air gun. At approx. 120 °C the material shrinks onto the cable diameter while the inner adhesive melts and fills all voids. Allow the connection to cool completely before putting it under load.
