HellermannTyton Connectivity HIS-3 Series Heat Shrink Tubing, 18mm Sleeve Diameter, 6mm Shrunk Diameter - 308-31807 HIS-3-18/6-PO-X-GNYE
This heatshrink tubing provides electrical insulation and cable identification in industrial settings. It is manufactured from cross‑linked polyolefin to deliver shrinkable sleeving that resists combustion and avoids halogen emissions, making it suitable for control cabinets, wiring looms and junctions where reduced smoke and corrosive gases are required.
Features & Benefits
• 3:1 shrink ratio affords tight conformal coverage
• Flame‑retardant construction reduces fire propagation risk
• Halogen‑free composition minimises corrosive gas release
• 4m sleeve length supports long runs without joins
• Flame‑retardant construction reduces fire propagation risk
• Halogen‑free composition minimises corrosive gas release
• 4m sleeve length supports long runs without joins
**Applications**
• Suitable for colour‑coding wiring in control panels
• Ideal for protecting cable joints in automation systems
• Used for insulating conductor terminations in electrical installations
• Can be used for harness identification in vehicle and machinery looms
• Used with cable assemblies requiring reduced‑smoke materials

What shrink performance can I expect around irregular shapes?
The 3:1 shrink ratio enables substantial diameter reduction, allowing the material to conform tightly to connectors and uneven profiles while maintaining electrical isolation.
How does the material behave under heat application?
The cross‑linked polyolefin Matrix recovers and adheres to substrates when heated, providing mechanical strain relief and environmental sealing once fully contracted.
Which colours are available for Visual identification?
The sleeving is supplied in a combined green and yellow colour scheme commonly used for protective earth identification and safety marking.
What dimensional information defines its post‑shrink size?
After full recovery the internal diameter is 6mm, providing the finished clearance for insulated conductors and terminations.
