Ideal 46-352 Heavy Wall Adhesive Heat Shrink Tube 3:1

Ideal 46-352 Heavy Wall Adhesive Heat Shrink Tube

This 3:1 ratio heavy-wall heat shrink tube is built for electrical professionals and automotive technicians who need reliable environmental sealing on large conductors. The cross-linked polyolefin construction with adhesive lining creates a waterproof, solvent-resistant barrier after shrinking. It fits wire sizes from 1/0 AWG to 3/0 AWG and arrives in individual 9-inch black pieces. The semi-rigid material maintains structural integrity in harsh conditions.

Integration into wiring builds

The tube slides over oversized connectors or splices before shrinking to a 0.35-inch inside diameter with a 0.12-inch recovered wall thickness. A minimum shrink temperature of 248°F activates the adhesive flow for a permanent bond. No special tools beyond a standard heat gun are required, freeing up bench space for other termination tasks. The flame-retardant rating supports compliance in vehicle and industrial panels.

Sustained load behaviour

Rated for continuous operation from -55°F to 110°F, the tubing resists cracking in extreme cold and softening in engine-bay heat. UV resistance prevents degradation on exposed exterior runs over years of service. The adhesive seal remains intact through vibration cycles and thermal expansion without rework. Solvent resistance protects against automotive fluids and cleaning agents.
