ProductType -->Dual-Wall Heat–shrinkable Tubing

Dual-Wall Heat–shrinkable Tubing is manufactured by co-extrusion of irradiated crosslinking polyolefin and specifically designed hot melt adhesive. This tubing may be used in a wide variety of electrical applications, including back end connector sealing, breakouts, and connector-to-cable transitions. High expansion ratio makes it possible to repair most damaged cable jackets without removing connectors. The product is UL recognized and the file No is E180908.
