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.

Questions about this item
What shrink ratio does the 46-352 tube provide for a tight seal on large cables?
The tube shrinks at a 3:1 ratio, reducing from 1.1 in to .35 in inner diameter.
Does the adhesive lining stay intact when the tubing reaches its 110 F operating ceiling?
Yes, the cross-linked polyolefin with adhesive is rated from -55 to 110 F.
What minimum heat-source temperature is needed to activate the 248 F shrink point?
A heat gun or torch capable of at least 248 F is required to start shrinking.
