The WOER 4mm Industrial Grade Heat Shrink Tubing is a high-performance, cross-linked polyolefin sleeve engineered for superior electrical insulation, cable management, and environmental protection. It features a standard 2:1 shrink ratio, meaning it starts with an internal diameter of 4mm and shrinks down uniformly to approximately 2mm when heat is applied. Because it is "Industrial Grade," it offers enhanced resistance to harsh chemicals, oils, environmental weathering, and mechanical wear and tear compared to generic DIY alternatives. It is a staple component in automotive wiring harnesses, industrial machinery panels, consumer electronics, and drone/robotics battery builds.
Features :
- 2:1 Shrink Ratio : from 4mm down to ~2mm
- Flame Retardant & Safe : stringent industrial standards
- Excellent Dielectric Strength : safely sealing joints up to 600V to prevent short circuits
- Rugged Mechanical Durability : abrasions, puncture cuts, moisture, and chemical exposure, ensuring long-term strain relief

1 x Heat Shrink Sleeve 4mm Black Industrial Grade WOER (HST)
