RS PRO 399-978 Halogen Free Heat Shrink Tubing is a clear, flexible polyolefin tubing designed to provide robust cable insulation and protection. With a 25.4 mm sleeve diameter and a length of 1.2 meters, this tubing shrinks to half its original diameter (12.7 mm) when heated, adhering tightly to cables and wire joints. It features a 2:1 shrink ratio, meaning it shrinks to half its expanded size, ensuring a tight fit that seals and insulates effectively.
Manufactured from halogen-free polyolefin, this heat shrink tubing offers excellent electrical insulation properties and resists common fluids, solvents, and abrasion. It operates in temperatures ranging from -55°C to +135°C and shrinks at a minimum temperature of 110°C, making it suitable for a variety of industrial environments.
This tubing is transparent, enabling easy viewing of marker tags or identification marks on cables, which is invaluable for maintenance and troubleshooting. It meets stringent standards including BS3G 198 Part 3 11B, CSA C22.2 No. 198.1, IEC 60684-3-212 A&B, MIL SAE-AMS-DTL 23053/5 Class 1, and UL 224 VW-1, ensuring reliability in demanding applications.
Commonly employed in military, aerospace, electronics, industrial machinery, and construction, it protects cable joints, splices, and connectors by providing mechanical strain relief and environmental protection from moisture, dust, and chemicals.
The tubing has a 25.4 mm sleeve diameter and shrinks to 12.7 mm for secure insulation. Made from halogen free, flexible polyolefin material providing excellent durability. Operates between -55°C to +135°C, with a minimum shrink temperature of 110°C.
