RS PRO Heat Shrink Tubing Red 1.6 mm Sleeve Diameter 1.2 m Length Polyolefin Flame Retardant 2:1 Shrink Ratio 397-988

RS PRO 397-988 Heat Shrink Tubing is a high-quality polyolefin tubing designed to provide excellent insulation and protection for electrical cable joints and wire splices. Featuring a 2:1 shrink ratio, it shrinks to half its original diameter when heated, ensuring a tight, secure seal around cables and connectors.

The tubing has a sleeve diameter of 1.6 mm in its expanded form and shrinks to 0.8 mm, with a total length of 1.2 meters, making it suitable for diverse wiring needs. Constructed from flame retardant polyolefin material, it balances flexibility with durability and protects against environmental hazards such as moisture, dust, chemicals, and abrasion.

Operating within a temperature range of -55°C to +135°C, with short-term resistance up to 200°C, it meets rigorous industry standards including ASTM, MIL, UL, and SAE-AMS-DTL-23053/5 Class 1. This compliance ensures its suitability for military, aerospace, automotive, industrial machinery, and electronics applications.

The Heat Shrink Tubing effectively bundles and organizes wires, offers mechanical strain relief to prevent damage from bending or flexing, and provides electrical insulation for resistors, capacitors, and other components. Its bright red color also supports easy identification and color coding of cables in complex systems.

Typical use cases include protecting cable joints and in-line components like disconnect terminals, performing repairs on worn insulation, and providing environmental and mechanical protection in demanding industrial and commercial environments.

This product combines high technical performance with versatility, making it an essential component for electrical maintenance, repair, and assembly tasks in industrial, laboratory, construction, HVAC, and manufacturing sectors.

The tubing’s 2:1 shrink ratio allows it to accommodate size variations securely. Flame retardant properties enhance safety in electrical applications. Exceptional flexibility and durability enable long-lasting protection.

Its resistance to common solvents and fluids ensures reliability in harsh conditions. Meets multiple international standards for quality and safety compliance. Operates reliably over a broad temperature range, suitable for various environments.
