Automotive heat-shrink tubing designed for secure cable sealing and durable insulation. Ideal for electricians and car enthusiasts who need a reliable, long-lasting seal. Does the sourcing map Heat Shrink Tubing match the cables and repair jobs you tackle?
⚡ At a Glance
- • Material and protection: PE outer layer with hot-melt inner adhesive, engineered for insulation and robust sealing
- • Best for: Electrical maintenance, cable sealing, automotive manufacturing and DIY wiring repairs
- • Not ideal for: Very small gauge wires or delicate electronics requiring minimal heat application
PE heat shrink tubing supplied in a single 1 m length with a 32 mm inner diameter. Designed to cover and protect cable joins while improving mechanical stability and insulation.
Waterproof seals, with hot-melt inner adhesive
The inner layer is a hot-melt material that liquefies when heated and flows to fill gaps around the joint. Once cooled, the adhesive cures to form a continuous, dustproof and waterproof barrier.
Creates a reliable moisture and dust barrier around solder joints and exposed wires, reducing corrosion risk and improving long-term connection integrity.
High fit for varied bundles, with a 4:1 shrink ratio
A 4:1 shrink ratio means the tubing can reduce to one quarter of its original diameter after heating, allowing a wide initial diameter to adapt to smaller cable profiles.
Accommodates different cable thicknesses and multi-core bundles, producing a snug wrap that minimises movement and strain on the connection.
Durable insulation, with PE construction and heat resistance
Polyethylene outer material provides electrical insulation and resists elevated temperatures encountered during normal shrink operations. The material is chosen for long-term durability under mechanical stress.
Protects conductors from abrasion and environmental stress, helping to maintain safe insulation and reduce the chance of electrical faults over time.

❓ Frequently Asked Questions
Q: How does the tubing create a waterproof seal?
A: The inner hot-melt adhesive melts when heated and flows to fill gaps, then cools to form a continuous waterproof and dustproof layer.
Q: What size and quantity are included?
A: The package contains one 1 m length tube, with a 32 mm inner diameter and a 51 mm flat width.
Q: Which tasks is the tubing suitable for?
A: Suitable for wire end protection, solder joint corrosion protection, electronic component insulation, and use in electrical maintenance, automotive manufacturing and DIY repairs.
🏆 Our Verdict
Heat shrink tubing suits electricians, automotive technicians and DIYers who need a robust, waterproof seal for cable joints. The combination of a hot-melt inner adhesive, PE outer material and a large starting diameter with a 4:1 shrink ratio gives secure insulation and mechanical stability. Built for long-term protection and reduced maintenance, the tubing is a practical, enduring choice for repairs and assemblies.
