25-Piece Heavy-Wall Heat Shrink Kit

This pack contains 25 individual pieces of black heavy-wall heat shrink tubing designed for cable management and conduit protection. Each piece measures 6 inches in length and is made from cross-linked polyolefin with an adhesive lining. The tubing suits wire sizes ranging from 2 AWG to 4/0 AWG for professional electrical installations.

3:1 Shrink Ratio with Adhesive Seal

The tubing shrinks from a 1.1 inch inner diameter down to 0.37 inches, creating a 3:1 shrink ratio that conforms tightly around large conductors. An adhesive lining melts during heating to form a moisture-resistant seal around the connection. The rigid material provides abrasion, acid, alkali and UV resistance for harsh environments.

Replaces Standard Thin-Wall Tubing

Builders currently using thin-wall tubing without adhesive gain a thicker 0.12 inch wall after shrinking plus an environmental seal in one step. The operating range of -67 to 230 degrees Fahrenheit covers conditions where standard tubing would become brittle or melt. Buyers needing clear tubing or a higher shrink ratio will not find those options in this product.

Questions about this item

What is the lowest temperature the heavy-wall tubing can withstand before it becomes brittle?

The cross-linked polyolefin material stays flexible down to -67 °F, so it remains reliable in extreme cold environments.

How much adhesive-lined wall thickness remains after the tubing shrinks to its final diameter?

After shrinking at the 3:1 ratio the wall measures 0.12 in thick, providing a rigid, abrasion-resistant seal.

What wire-gauge range will fit inside the tubing before heat is applied?

The 1.1 in pre-shrink inside diameter accommodates conductors from 2 AWG up to 4/0 AWG.
