Brother International HSE221E Heat Shrink Tube Label

Product Description

The BROTHER INTERNATIONAL HSE221E is a heat shrink tube label cartridge designed for use with compatible Brother label printers. The cartridge produces printed heat shrink tubing that, when exposed to heat, contracts at a 3:1 ratio to form a tight, secure sleeve around wires, cables, and terminals. At 0.35 inches wide and 4.9 feet in length, the cartridge provides enough material for labeling a variety of conductor sizes. Electricians and low-voltage installers use this cartridge to create durable, professional wire identification labels that resist abrasion, moisture, and high temperatures common in panel and equipment installations.

This heat shrink label cartridge is suited for electrical contractors, industrial maintenance technicians, and data/communications installers who need reliable wire and cable identification. It is commonly used during panel builds, wire harness assembly, and structured cabling installations where permanent, legible wire labels are required. The 3:1 shrink ratio allows the printed tubing to conform tightly to conductors and connectors after heat application, ensuring labels stay in place throughout the life of the installation.

Key Features

• 3:1 shrink ratio provides a secure, conforming fit over wires, cables, and connectors
• 0.35-inch (8.9 mm) width accommodates a range of conductor and terminal sizes
• 4.9-foot (1.5 m) cartridge length yields multiple labels per cartridge
• Printed heat shrink tubing resists abrasion, moisture, and heat after shrinking
• Drop-in cartridge format for fast, tool-free loading into compatible Brother label printers

Compatibility

Designed for use with compatible Brother HSe-series label printers that accept heat shrink tube cartridges. Consult the printer compatibility guide for your specific model before ordering.

Installation Notes

Installation is performed by electricians and low-voltage technicians using a compatible Brother label printer and a heat gun or dedicated heat shrink tool. Print the label, slide the shrink tubing over the wire or terminal, and apply heat evenly until the tubing shrinks to its final diameter. De-energize all circuits before applying labels to live panels or wiring in accordance with applicable NEC requirements. Allow the tubing to cool completely before restoring power or making connections.
