5-Count 6.4mm 3-in Heat Shrink Tubing

Gardner Bender heat shrink tubing is designed for cable insulation, marking and bundling in electrical applications. This polyolefin tubing shrinks when heated to create a secure, protective covering that seals and insulates wire connections and cable joints. It provides mechanical, abrasion and moisture protection to help guard against damage and environmental exposure.

The tubing resists common fluids and solvents, and is flame retardant, meeting UL 224 VW-1 standards for electrical safety. With a 2:1 shrink ratio, it reliably reduces from 1/4 inch expanded diameter to 1/8 inch recovered diameter after heating, creating a snug fit around cables of appropriate size. This five-pack of 3-inch lengths offers convenient, ready-to-use pieces for multiple connections and repairs.
