3:1 Adhesive Lined Polyolefin Heat Shrink Tubing
Flame retardant, flexible Polyolefin heat shrink tubing lined with a moisture proof sealant. For use in repairing and protecting cable jackets, outdoor connections and splices. Upon shrinking, the inner adhesive melts and flows while outer tubing shrinks to conform to substrate. Ideal for strain relief, sealing, encapsulating, moisture and corrosion protection of wires and termials.
