Product Details

Dual wall (adhesive lined) 3:1 heat shrink tubing is made from a specially formulated, cross-linked polyolefin that is co-extruded with a meltable adhesive sealant. It offers excellent electrical, chemical and physical properties. This tough, flexible, flame retardant tubing can be used for electrical insulation, wire bundling, lightweight harnessing, and wire strain relief in a variety of home, commercial, industrial and military applications.

When heated and the tubing begins to shrink, the inner adhesive layer begins to melt and flow (similar to hot melt glue). When the tubing has shrank and cooled, the inner layer forms an adhesion layer between the tubing and the wire or component, providing a protective water-tight seal. 
It is an excellent way to terminate the ends of your Braided Sleeving, creating a tight, professional finish. 
The flame retardant jacket of 3:1 heat shrink tubing is tested and approved for use under UL VW-1 and CSA OFT material standards. Additionally, it is in compliance with RoHS, the European directive on the Restriction of Hazardous Substances.
