Product Details
The B-342 Polyolefin Permasleeve material is a non-adhesive, heat-shrinking sleeve designed for permanent identification of wires or cables. This 3:1 heat-shrinkable wire sleeve fits snugly around wires, providing maximum insulation protection while resisting chemicals, grease, oil, and cleaning agents, making it suitable for harsh environments. The polyolefin wire marking sleeves feature a smudge-proof finish that prints black text on a white background for clear labeling. They are cold resistant and flame-retardant, with an operating temperature range of -67° F to 275° F (-55° C to 135° C). Permasleeve labels are ideal for use by electrical contractors, maintenance crews, and industrial professionals, offering a combination of speed, ease of use, and permanence for long-lasting, high-quality identification.
