RS PRO Heat Shrink Tubing Black Polyolefin 9.5mm Sleeve Diameter x 12m Length 2:1 Ratio 666-903

RS PRO 666-903 Heat Shrink Tubing is a high-quality black polyolefin tube designed for insulating, protecting, and bundling wires, cables, and electronic components. With a sleeve diameter of 9.5mm and a 12-meter length, this tubing offers a practical solution suitable for a wide range of industrial, automotive, and electronic installations.

The tubing shrinks radially to half its original diameter, thanks to its 2:1 shrink ratio. When heated to at least 90°C, the sleeve tightly seals and conforms to cable joints or connectors, ensuring secure insulation and environmental protection. The material is flexible, flame-retardant, and durable, derived from polyethylene to deliver robust performance in demanding environments. Its excellent electrical insulation properties help safeguard against shorts, voltage leaks, and external factors like moisture and chemicals.

RS PRO heat shrink tubing is widely used in military and aerospace installations, automotive harness repairs, industrial machines, electronic devices, and construction machinery. It is ideal for protecting cable splices, providing strain relief, and repairing worn or damaged insulation. Additionally, the tubing allows color-coded identification and bundling for neat and organized cable management.

The tubing operates reliably between -55°C and +135°C, with short-term resistance up to 200°C. It is resistant to common industrial fluids and solvents. The supplied 12-meter length is convenient for multiple installations or repairs, making it economical for commercial and industrial users.

Installation is simple: cut the tube to desired length, slide onto the wire or cable, and apply heat using a standard heat gun until the tubing shrinks and fits securely. The 9.5mm diameter suits a variety of cable sizes, and after shrinking, provides a tight, protective seal with a shrunk diameter of 4.8mm.

Industries such as electronics manufacturing, automotive service, military equipment, construction machinery, and facility maintenance benefit greatly from using RS PRO 666-903 heat shrink tubing for insulation, bundling, strain relief, and environmental protection needs.

Flexible polyolefin tubing delivers reliable insulation for wires and cables. 2:1 shrink ratio ensures secure fitting and adapts to cable diameter changes. Flame-retardant material enhances safety in electrical and industrial systems.
