This 6.4mm - 3.2mm heat shrink tubing provides a popular mid-to-large diameter option, ideal for heavier domestic and light commercial electrical work. The 12-metre reel length offers substantial coverage for projects requiring reliable protection of medium-gauge cables, including power tool repairs, trailer wiring, and robust automotive applications. The diameter range suits a wide variety of common electrical cables, making it an excellent general-purpose choice for professional tradespeople. When heated to 90°C, the 2:1 shrink ratio contracts the tubing from 6.4mm to 3.2mm, forming a tight, moisture-resistant seal. The thin-wall design maintains handling flexibility whilst the RoHS compliant construction meets environmental standards. Supplied in a practical dispenser, the tubing can be cut to exact lengths as required, reducing waste and improving efficiency.
