Why Choose the Partex HSDW3-4.8 Adhesive-Lined Heat Shrink Tubing?
The Partex HSDW3-4.8 is a versatile 3:1 adhesive-lined heat shrink tubing designed to provide electrical insulation, moisture protection and mechanical protection for wires, cables and electrical connections. As part of the Partex HSDW3 dual-wall heat shrink tubing range, it combines a heat-shrinkable outer sleeve with an internal adhesive lining to create a secure protective covering around compatible electrical components.
Featuring a nominal supplied internal diameter of 4.8 mm and a nominal fully recovered diameter of 1.6 mm, this tubing offers a 3:1 shrink ratio that accommodates a range of cable and connection sizes. When heated correctly, the outer tubing contracts while the internal adhesive softens and flows around the underlying surface, helping form a moisture-resistant seal.
The HSDW3-4.8 is particularly suitable for electrical installations where conventional single-wall heat shrink tubing may not provide sufficient environmental protection. Its dual-wall construction makes it a practical choice for cable splices, wiring harnesses, electrical terminals and industrial maintenance applications requiring additional insulation and sealing.

Reliable Moisture Protection and Electrical Cable Sealing
Adhesive-lined heat shrink tubing provides additional protection compared with conventional single-wall sleeving by combining heat shrink technology with an internal sealing adhesive. During installation, suitable heat causes the outer sleeve to contract while the adhesive softens and flows around the cable or component, helping reduce moisture ingress and contamination.
The Partex HSDW3-4.8 is designed for applications requiring both insulation and sealing around smaller cables and electrical connections. Its 3:1 shrink ratio enables the tubing to accommodate variations in cable diameter and connection geometry, making it useful for protecting wire joints, cable transitions and electrical terminations.
For best results, the tubing should be selected to suit the diameter of the cable and the largest component it must pass over. Correct heating, suitable surface preparation and compatible cable materials are important for achieving effective adhesive bonding and environmental protection.
Typical Applications
- Electrical cable splices and wire joint insulation.
- Moisture-resistant protection of compatible electrical connections.
- Industrial wiring harnesses and cable assemblies.
- Electrical terminals and cable termination protection.
- Control panel wiring and automation equipment.
- Automotive and machinery electrical maintenance.
- Cable repairs and protective sleeving in suitable industrial environments.
