ES321 - 3:1 Polyolefin Heat Shrink Tubing
Highly Flame-Retardant, Flexible, Low Shrink Temperature, Polyolefin Tubing 3:1
Applications
3:1 polyolefin heat shrink tubing is the cost- effective choice for many commercial and military applications; electrically insulates and protects in-line components, disconnect terminals and splices. Bundles wires for very flexible light-duty harnesses. Strain-relieves electrical wire connections for commercial applications. Identifies or color-codes wires, cables, terminals, and components. Higher shrink ratio is more suitable for applications with irregular shapes.
