Raraion 2:1 Heat Shrink Tubing Flexible Polyolefin – Black - 4.8mm 5m
Professional-grade 2:1 heat shrink tubing. Flame-retardant, 25kV dielectric strength. For insulation, protection & harness work.
The Raraion 2:1 Heat Shrink Tubing is a high-quality, versatile insulating sleeve crafted from flexible, flame-retardant polyolefin. Engineered to meet rigorous industrial standards, it is manufactured to MIL-1-23053/5 Grade 3, ensuring reliability and safety in demanding applications. This tubing is ideal for providing essential insulation, protection, and clear identification for wires, cables, and connectors.
Its primary function is to create a durable, sealed barrier against abrasion, moisture, chemicals, and short circuits. When heat is applied, the tubing shrinks uniformly to half its original diameter (a 2:1 shrink ratio), forming a tight, conformal fit around the object it protects. This makes it exceptionally useful for bundling wires, repairing cable jackets, and creating professional, strain-relief terminations in cable harness assemblies.
Featuring a robust dielectric strength of 25 kV, this heat shrink tubing offers excellent electrical insulation properties, safeguarding against high-voltage environments. Its flame-retardant nature adds a critical layer of safety, helping to prevent the spread of fire in electrical systems. The black colour provides a professional, low-profile finish that is resistant to UV light and suitable for both indoor and outdoor use.
Common applications extend across numerous fields including automotive wiring, marine electronics, aerospace, telecommunications, and general industrial maintenance. It is a staple for electricians, engineers, and DIY enthusiasts looking for a reliable solution to organise, protect, and insulate electrical connections. Supplied in a convenient length, it is easy to cut to size for any project, ensuring minimal waste and maximum utility.
With its combination of flexibility, durability, and high-performance specifications, Raraion heat shrink tubing is an indispensable component for anyone requiring a professional-grade insulating solution that delivers
