BRADY PermaSleeve Heat-Shrink Tubing, 3:1, White, 18-12 AWG, 0.187 in Dia, 1.5 in L, 100/Roll

Heat-shrink sleeves engineered for permanent, high-legibility wire and cable identification in demanding environments. The B-342 polyolefin material delivers a 3:1 shrink ratio, conforming tightly to irregular surfaces for crisp, smudge-proof legends that withstand abrasion, chemicals, and UV exposure.

Advantages

These sleeves provide a secure, non-adhesive grip once shrunk, eliminating flagging and peeling. The matte white finish ensures excellent contrast for thermal transfer printing, while the material's resistance to oils, solvents, and humidity guarantees long-term readability in industrial settings. The 3:1 ratio accommodates a wide range of wire diameters, reducing inventory needs.
