Heat shrink tube 6 mm x 1.5 m, black on yellow, replacement for Brother HSE-211BY

Heat shrink tube 6 mm x 1.5 m in black on yellow is a flexible, heat-activated sleeving designed for cable identification and protective insulation. Before shrinking the tube measures 6 mm in diameter and has a total length of 1.5 m, and it serves as a compatible replacement for label maker consumables used in marking wires and components. The contrasting black-on-yellow surface ensures legible printed or handwritten text, while the heat-shrink material conforms tightly to cables, joints and connectors to reduce abrasion and provide basic moisture resistance.

Advantages

This heat shrink tube combines clear high-contrast marking capability with physical protection. Its 6 mm pre-shrink diameter fits a wide range of single conductors and small cable bundles, and the material shrinks to form a snug, low-profile sleeve that resists movement along the wire. The yellow background with black print area improves visibility and readability of labels. The product is compatible with common label maker tape sizes used for cable marking and is suitable for on-site electrical and data-cabling work.

Suitable for

• Marking individual wires and small cable bundles
• Insulating and protecting solder joints, splices and connectors
• Creating durable labels with label printers or permanent markers
• Organizing wiring in control panels, telecom racks and automotive harnesses

Key specifications

• Pre-shrink diameter: 6 mm
• Length: 1.5 m total
• Colour: black text/marking surface on yellow sleeve
• Material: heat-shrinkable polymer (heat-activated sleeving)
• Shrink ratio: typical for general-purpose tubing to provide a tight fit (material conforms to cable when heated)

How to use

Slide a suitable length of the heat shrink tube over the cable or joint before making the final connection if covering a splice. Mark the sleeve with a label printer or a permanent marker while unshrunk for best legibility. Apply heat evenly using a heat gun, hot air tool or controlled flame at a safe distance until the tubing contracts and forms a tight seal around the conductor and connector. Allow the sleeve to cool to complete the shrink process and verify that the marking remains legible.

Usage recommendations

For reliable results, use a temperature-controlled heat gun set to the manufacturer-recommended range for general-purpose heat-shrink polymer and keep the gun moving to avoid overheating a single spot. Choose an appropriate sleeve length so markings stay visible after shrinking, and test on a scrap piece if exact shrink fit is critical. Avoid exposing the sleeve to prolonged open flame and follow standard electrical safety precautions when working on live circuits.
