Heat Shrink Tubing Ergom TCREL BOX 3.2/1.6 BK 15m — thin-wall flexible heat-shrink sleeve

Ergom TCREL BOX 3.2/1.6 BK is a thin-wall flexible heat-shrink tubing supplied on a 15 m roll. The sleeve reduces from 3.2 mm to 1.6 mm diameter when heated, providing reliable electrical insulation, mechanical protection and strain relief for individual wires, connector joints and small harness sections. Its flexible material follows bends and fits tightly after shrinking to create dielectric separation and improve cable appearance and routing in automotive, industrial and consumer electronic assemblies.

Advantages

The thin-wall construction ensures a compact fit with minimal added bulk while maintaining sufficient mechanical protection. Flexible material conforms to irregular shapes and tight bends, while the controlled shrink ratio provides consistent results across multiple applications. Supplied on a 15 m roll, the tubing supports continuous operations and reduces the need for frequent reloading. The black color offers discrete coverage and improved visual uniformity for wiring runs.

Suitable for

• Insulating exposed wire splices and solder joints
• Providing strain relief at connector exits and terminations
• Repairing or bundling small wire harnesses
• Protecting wires in automotive and industrial control applications
• Neat covering of consumer electronics internal wiring

Key specifications

• Material: thin-wall heat-shrinkable polymer (flexible)
• Shrink ratio: from 3.2 mm nominal to 1.6 mm nominal diameter when heated
• Length per roll: 15 m
• Color: black
• Application temperature: suitable for standard heat sources used for heat-shrink tubing

How to use

Slide an appropriate length of tubing over the wire, splice or connector area before making the joint when possible. Apply heat evenly using a heat gun, lighter with care, or other controlled heat source until the tubing has fully conformed to the underlying profile. Allow the tubing to cool so it sets firmly around the component and inspect the fit to ensure full shrinkage and secure coverage. Trim excess tubing with scissors or a cutting tool prior to installation if needed.

Usage recommendations

For consistent results, select tubing with a slightly larger pre-shrink diameter than the component to be covered and heat progressively from the center outward. Avoid direct flame contact for prolonged periods to prevent damage to insulation or surrounding components; a dedicated heat gun at moderate settings is generally recommended.
