RS PRO Heat Shrink Tubing Blue 2.4 mm Sleeve Diameter x 1.2 m Length Polyolefin 2:1 Ratio 397-887

RS PRO Heat Shrink Tubing Blue 2.4 mm Sleeve Diameter x 1.2 m Length model 397-887 is a highly flexible polyolefin tubing designed to deliver optimal electrical insulation and mechanical protection for cable joints and wiring connections. With a 2:1 shrink ratio, this tubing shrinks to half its original diameter when heat is applied, ensuring a secure and custom fit around terminals, splices, and bundled wires.

The material used is polyolefin, selected for its excellent flame-retardant properties and durability. This makes it suitable for demanding industrial, automotive, aerospace, and electronics environments, where resistance to moisture, dust, chemicals, and abrasion is essential. The tubing is colour coded in blue, aiding in harness organization and rapid identification of cables and components.

Operating reliably within a wide temperature range from -55°C to +135°C, and tolerating up to 200°C for short periods, this tubing is engineered to meet professional and industrial standards including UL, MIL, and ASTM. The minimum shrink temperature is 90°C, enabling easy and efficient installation using standard heat guns.

Polyolefin heat shrink tubing is widely used for a variety of functions: electrical insulation, environmental sealing, mechanical strain relief, bundling and organizing harness wires, and for repairs to existing worn or damaged cable insulation. In addition, its 2:1 shrink ratio allows it to fit over components with varying diameters, providing versatile application coverage.

This tubing protects components like resistors, capacitors, and connectors against harsh environmental conditions and mechanical stress. Its flexibility, rapid shrinking characteristics, and durable construction ensure long-term performance and safety across manufacturing, laboratory instrumentation, HVAC systems, water treatment, and commercial installations.

Provides excellent electrical insulation and environmental protection for wires and cable joints. Built from flexible, flame-retardant polyolefin material for enhanced durability. Features a 2:1 shrink ratio, reducing sleeve diameter from 2.4 mm to 1.2 mm for tight fitting.

Resistant to moisture, chemicals, and abrasion, ensuring long-term reliability in industrial applications. Suitable for automotive, aerospace, electronics, and construction machinery wiring tasks. Colour coded in blue for easy cable identification and harness organization.

Operating temperature range from -55°C to +135°C, with short-term tolerance up to 200°C. Meets multiple industrial standards, including UL, MIL, and ASTM. Explore more cable insulation solutions in the Heat Shrink Tubing range from RS PRO and other leading brands at EnvMart.
