ES221 - 2:1 Polyolefin Heat Shrink Tubing
Highly Flame-Retardant, Flexible, Low Shrink Temperature, Polyolefin Tubing
2:1 Polyolefin Tubing Applications
This Polyolefin tubing shrinks in a 2:1 ratio. The cost-effective choice for many commercial 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.
