Diameter Before Shrinkage



Shrink-N-Shield® (2:1) combines two proven technologies into a single, easy-to-install product for adding EMI protection to smaller wire and cable bundles. Shrink-N-Shield® is ideal for cables diameters of 1/2" and less. Shrink-N-Shield® is comprised of SAE-AMS-DTL-23053/5 heat shrink tubing and Zippertubing's Z-3250-CN conductive cloth which provides outstanding shielding properties. Shrink-N-Shield® makes adding an EMI shield and secondary insulation jacket to wire or cable a snap. The materials combined have an operational temperature range of -40 to 250°F. This product is supplied in four foot long sticks.
