Brady’s non-adhesive, printable heat shrink wire marking sleeves fit around wires or cables for maximum insulation protection and permanent identification. Brady’s heat shrink sleeving is a full-circle design that provides fast and permanent wire marking. Clear, legible text can be printed on the wire and cable sleeving with a Brady printer for reliable wire identification. Brady heat shrink sleeving materials excel in extreme environments, including temperature fluctuations and environments that require abrasion and chemical resistance. Brady offers a variety of materials available to print using thermal transfer and dot matrix printers. B-342 3:1 heat shinkable sleeves for wire identification and insulation purposes are fade resistant and fire retardant. B-342 is available in white, yellow, black, red, orange, green, blue, violet, pink, gray, and brown.
