Brady PermaSleeve heat shrink labels M7-1000-1-342-YL are designed for demanding wire marking applications where durability, compliance, and readability must be maintained over the life of the system. Built from heat-shrink polyolefin, these sleeves provide a secure, permanent identification solution for electrical panels, control cabinets, and wire harness assemblies.
With a 3:1 shrink ratio, the sleeves conform tightly to wires and cables after heat application, eliminating gaps that can lead to label slippage or misidentification. This is particularly important in high-vibration environments or densely packed control systems where labeling must remain stable over time.
The Brady M7-1000-1-342-YL labels are engineered to resist a wide range of environmental stressors, including fuels, oils, solvents, and UV exposure. It also performs across extreme temperature ranges, making it suitable for both indoor and outdoor installations. The self-extinguishing property enhances safety in electrical environments, aligning with industry standards such as UL 224 and MIL-STD-202.
When paired with thermal transfer printing and high-performance ribbons like the Brady R6600, users achieve crisp, high-resolution text and barcode output. This supports clear identification, improves maintenance efficiency, and ensures compliance with labeling requirements in industrial and DataCom applications.
