RS PRO Heat Shrink Tubing Polyolefin Red 6.4 mm Sleeve Diameter x 1.2 m Length 2:1 Ratio 398-290

RS PRO 398-290 Heat Shrink Tubing is a specialized cable insulation product engineered from flexible polyolefin material. Its red colour, 6.4 mm sleeve diameter, and a length of 1.2 m make it suitable for a wide range of electrical, industrial, and automotive applications where cable integrity and protection are crucial. The tubing features a 2:1 shrink ratio, meaning it shrinks to half its original diameter upon heating, providing a tight, secure fit around wires, connectors, and cable splices.

Designed for high flexibility and durability, this tubing delivers excellent electrical insulation and mechanical strain relief. It serves both as a primary protection against abrasion and environmental factors such as moisture, dust, and chemicals, and as a secondary means of colour-coded cable identification. Flame retardant capabilities improve safety and reliability in environments subject to fire hazards, while resistance to fluids and solvents ensures long-term durability even in corrosive conditions.

RS PRO’s polyolefin heat shrink tubing operates reliably across a wide temperature range from -55°C to +135°C and withstands temperatures up to 200°C for brief periods. The tubing achieves shrinkage at a minimum temperature of 90°C, enabling fast, efficient installation in field, manufacturing, or maintenance settings. With its compliance to SAE-AMS-DTL-23053/5 Class 1, CSA and UL standards, the product suits applications in military, aerospace, electronics, construction machinery, and broader industrial contexts.

Heat Shrink Tubing is vital for electrical insulation, environmental sealing, mechanical protection, and strain relief in resistors, capacitors, wiring harnesses, and splices. It is easy to cut to required length and install, allowing for effective repairs or upgrades of existing cable insulation.

Its colour-coded identification simplifies cable management in complex assemblies, supporting safe and organized installation in industrial, laboratory, automotive, and commercial environments. Bundling and organising harness wires, cable, and tubing are made more efficient with this tubing’s robust design.

This product is ideal for frequent use in maintenance departments, assembly lines, laboratory setups, and manufacturing facilities where trusted cable sealing and identification are required.
