3M Black Heat Shrink Tubing 1.2 mm Sleeve Diameter x 12 m Length Polyolefin Flame Retardant HSR Series HSR 1,2

3M HSR 1,2 Heat Shrink Tubing is a black polyolefin tube with a 1.2 mm sleeve diameter and 12 meters in length, designed to provide reliable insulation and protection in electrical and automation wiring applications.

This heat shrink tubing features a 2:1 shrink ratio, allowing it to contract to half its original diameter when heated, creating a tight, protective seal around wires and splices. Being thin-walled, it offers efficient insulation without adding significant bulk.

The tubing remains flexible after shrinkage due to the absence of hot melt adhesive, thus accommodating wiring flex and movement. It is flame retardant, enhancing safety where wiring is exposed to higher temperatures or potential ignition sources.

Applications include protection of electronic components, wire splices, and bundling of wires in automotive, truck, and marine environments where harsh conditions require durable cable protection.

The tubing is supplied in a dispenser box for convenient handling and cutting to length according to application needs. The tubing’s flexibility allows easy installation in complex wiring harnesses. Its flame retardant rating meets safety needs for electrical assemblies.

The 2:1 shrink ratio ensures a secure and sealed fit on splices and joints. Black color provides standard insulation identification in wiring systems. Constructed from durable polyolefin material for long-lasting performance.

3M’s Heat Shrink Tubing from the HSR Series represents a trusted solution for industrial, automotive, marine, and commercial wiring insulation needs, ensuring enhanced protection and longevity.
