RS PRO Polyolefin Heat Shrink Tubing Yellow, 12.7 mm Sleeve Diameter, 1.2 m Length, 2:1 Ratio, Flame Retardant 399-625

RS PRO 399-625 Polyolefin Heat Shrink Tubing is a high-quality solution designed for professional cable protection and insulation. Featuring a sleeve diameter of 12.7 mm and a length of 1.2 meters, this tubing is suited to a wide range of cable joints and wiring tasks. The yellow colour enables easy identification and organization of wire bundles and electrical installations.

Constructed from flexible, flame-retardant polyolefin, the tubing offers outstanding resistance to solvents, fluids, and abrasion. Its 2:1 shrink ratio means the sleeve shrinks to half its original diameter, providing a tight and secure seal around cables, wire splices, terminals, and components. The tubing is halogen-free for installations requiring low-toxicity performance, and it meets or exceeds 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, UL 224 VW-1 E48762, and VG 95343 Part 5 standards.

With an operating temperature range from -55°C to +135°C (and up to 200°C for short durations), RS PRO 399-625 is designed for challenging environments. The shrink temperature is a minimum of 90°C, ensuring compatibility with standard heat sources such as heat guns.

This heat shrink tubing is ideal for use in electrical insulation, environmental protection against moisture and chemicals, mechanical strain relief, and bundling of harnesses in military, aerospace, automotive, industrial machinery, electronics, and construction fields. It also facilitates repairs on worn or damaged wire insulation and enables colour-coded identification of cables and components.

Industrial and laboratory engineers trust RS PRO Polyolefin Heat Shrink Tubing for dependable performance in manufacturing, water treatment, automotive wiring, construction equipment, and electrical laboratories. It is widely used for protecting and sealing cable joints, in-line components, and wire splices, as well as providing strain relief and robust mechanical protection.

Durable polyolefin material resists abrasion and solvents. 2:1 shrink ratio delivers a secure fit for diverse cable applications. Yellow colour enables clear identification and organization. High flexibility supports easy installation in tight spaces.
