Heat-shrinkable tubing for fiber optic closures

5.71 € – 9.29 € without VAT

High-quality heat-shrinkable tubing (heat-shrink sleeves) with an inner hot-melt adhesive lining, designed for secure and watertight entry of optical cables into underground or aerial fiber optic splice closures.

These entry kits provide complete protection against moisture, dust, and mechanical stress, guaranteeing long-term closure sealing under the most demanding operating conditions.

Key Features and Benefits:

High Sealing Performance (IP68): The thermoplastic adhesive layer on the inside melts during heating and evenly fills all gaps between the cable armor/jacket and the closure entry port.

Environmental Resistance: The material is resistant to UV radiation, harsh chemicals, acids, alkalis, and temperature fluctuations.

Mechanical Strength: Heavy-wall polyethylene construction protects the cable entry from tension, crushing, and vibration.

Versatility: Suitable for both single cables (Single Cable Ports) and dual oval entries (Oval Port / Branching) for branching or looping cables.
