3:1 Single wall heat shrink tubing is made from a specially formulated, cross-linked polyolefin. 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. The flame retardant jacket of 3:1 single wall heat shrink tubing is in compliance with RoHS, the European directive on the Restriction of Hazardous Substances.
3:1 heat shrink tubing will slide easily over inline splices and connectors, and shrink down to 33% of its original diameter to fit snugly over any wire, hose or cable management project. it is an excellent way to terminate the ends of your Braided Sleeving, creating a tight, professional finish.
Typical applications include: Insulation, Wire Identification, Wire Bundling, Mechanical Protection, Color Coding, Lightweight Harnessing, Physical/Electrical Protection of Components, Strain Relief, and Solder Insulation
Note: Inside Diameters for Heat Shrink Tubing are measured as ROUND Tube, Not FLAT
UL Listed, File E536025
REACH Compliant
