RS PRO Halogen Free Clear Polyolefin Heat Shrink Tubing 50.8 mm Sleeve Diameter x 1.2 m Length 2:1 Ratio 399-990

RS PRO 399-990 Halogen Free Heat Shrink Tubing is made from high-quality clear polyolefin, offering a flexible and durable solution for insulating and protecting electrical cables and wire joints. With a 2:1 shrink ratio, it shrinks to half its original diameter, allowing secure sealing around cables and connectors. The tubing measures 50.8 mm in sleeve diameter and extends 1.2 meters in length, ideal for covering larger cable sections.

The material is halogen-free, enhancing safety by minimizing toxic fume emission during fire incidents. It operates reliably within a broad temperature range from -55°C to +135°C, making it suitable for harsh industrial and aerospace environments. The minimum shrink temperature is 110°C, allowing controlled and efficient installation with heat guns or similar heat sources.

This heat shrink tubing is approved to rigorous standards including SAE-AMS-DTL-23053/5 Class 1, IEC 60684-3-212, CSA C22.2 No. 198.1, UL 224 VW-1, and others, guaranteeing compliance and performance in demanding applications. Its clear construction enables users to view cable markers or identification tags through the sleeve after installation.

Flexible polyolefin construction provides excellent electrical insulation, robust abrasion resistance, and protection from chemicals and common solvents. This makes it ideal for use in military, aerospace, industrial machinery, electronics, and construction sectors where cable protection and environmental sealing are critical.

Heat shrink tubing shields cable joints from moisture, dust, and mechanical strain, extending cable life and ensuring reliable electrical performance. It is widely used for insulating resistors, capacitors, wire splices, disconnect terminals, and repairing worn cable insulation.

This tubing has a 50.8 mm sleeve diameter and 1.2 m length to cover substantial cable sections. Designed to shrink to half its original diameter at a minimum shrink temperature of 110°C. Offers excellent electrical insulation and abrasion resistance within an operating temperature range of -55 to +135 degrees Celsius.

Halogen-free composition improves safety by preventing toxic emissions in case of fire. Complies with SAE-AMS-DTL-23053/5 Class 1 and multiple international standards for quality and reliability. Clear transparent construction permits visibility of cable markers and identification underneath.
