ES421 - 4:1 Polyolefin Heat Shrink Tubing
Highly Flame-Retardant, Flexible, Low Shrink Temperature, Polyolefin Tubing 4:1
Applications
2:1 polyolefin heat shrink tubing is ideal for repairing harnesses or cables. The shrink ratio will allow this tubing to pass over a large diameter connector or transition and then shrink down onto a smaller diameter jacket. Can insulate or protect a substrate of varying dimensions.
