BRADY PermaSleeve Heat-Shrink Wire Marker Sleeve, Black on White, 0.75 inch Width, 21 ft, 16-10 AWG

Wire and cable marking reaches a new level of durability with the BRADY PermaSleeve Heat-Shrink sleeve. This black-on-white polyolefin marker shrinks to a tight, permanent fit when heated, creating a label that resists abrasion, chemicals, fuels, oils, weather, and UV exposure. Compatible with BRADY BMP21-PLUS, BMP21-LAB, M210, and M211 thermal transfer printers, it delivers crisp, legible identification for 16-10 AWG wires. The 2:1 shrink ratio and 0.75-inch flattened width accommodate wire diameters from 2.64 to 5.26 mm, making it a versatile choice for electrical, datacom, and industrial applications.

Advantages

Heat-shrink sleeves offer unmatched permanence compared to adhesive labels. Once recovered, they become an integral part of the wire insulation, eliminating the risk of peeling or flagging. The matte finish reduces glare, ensuring readability in varied lighting conditions. With a wide operating temperature range of -55°C to 135°C, these sleeves perform reliably in extreme environments. UL Recognized, CSA Accepted, and RoHS Compliant, they meet rigorous safety and environmental standards.

Suitable for

• Wire and cable identification in electrical panels and control cabinets
• Datacom and network infrastructure labeling
• Harsh environment applications requiring chemical and abrasion resistance
• Maintenance and repair operations where permanent marking is essential
• Compliance labeling for safety and regulatory requirements

Recommendations

For best results, use with BRADY BMP21-PLUS or BMP21-LAB label printers. Ensure the wire is clean and dry before applying the sleeve. Heat evenly with a heat gun until the sleeve conforms tightly to the wire. Store in a cool, dry place away from direct sunlight to maintain material integrity.
