Heat shrink tube 9 mm x 1.5 m black on white — replacement for BROTHER HSE-221

Heat shrink tube 9 mm x 1.5 m black on white — replacement for BROTHER HSE-221 is a thermal shrink tubing designed for marking, insulating and protecting cable joints and wire terminations. The product features black printed characters on a white shrinkable sleeve with an initial 9 mm diameter and a 1.5 m total length, intended for use with compatible heat-shrink label printers and heat tools that accept 9 mm tubing. It provides a durable printed identification surface and mechanical protection once shrunk, helping to organize wiring and prevent abrasion at connection points.

Advantages

This heat shrink tube offers clear, high-contrast black-on-white printing for easily readable labels after shrinking. The tubing provides reliable insulation and abrasion resistance once heat is applied, improving the longevity of marked connections. Its 9 mm diameter before shrinking and 1.5 m total length make it suitable for multiple labels or longer identification runs, and compatibility with common 9 mm thermal shrink systems ensures straightforward replacement installation.

Suitable for

• Marking and identifying electrical wires and cables
• Insulating solder joints and crimp connections
• Telecommunications and network cable labeling
• Home electrical repairs and DIY wiring projects

Key specifications

• Initial tube diameter: 9 mm (pre-shrink)
• Length: 1.5 m total
• Print color: black characters
• Background color: white
• Material: heat-shrinkable sleeving suitable for thermal printing and shrinking
• Function: cable marking, insulation and abrasion protection after heat shrinking

How to use

Print desired text using a compatible thermal shrink label printer or prepare the sleeve in a compatible heat-shrink system that accepts 9 mm tubing. Slide the printed sleeve over the cable or connection point to be labeled, position it accurately, then apply heat evenly with a compatible heat gun or shrink tool until the sleeve conforms tightly to the wire and the print is legible. Allow the tubing to cool and inspect the adhesion and print clarity before use.

Usage recommendations

Use a heat source and printer recommended for 9 mm thermal shrink tubing to ensure clear printing and uniform shrinking. Avoid overheating to prevent damage to cables and maintain sufficient distance from sensitive components while shrinking. Store the tubing in a dry, cool place away from direct sunlight to preserve print quality and material properties.
