Heavy-Wall Heat-Shrink Conduit

This 3M adhesive-lined conduit protects large-gauge cables with a semi-rigid polyolefin wall that resists flame, abrasion, acid and alkali. Each piece shrinks from 4.5 in to 1.5 in inner diameter at a 3:1 ratio, leaving a .17 in wall after recovery. The 48 in length suits long-run sealing in harsh environments.

For Sealing Large-Cable Bundles

Builders insulating 1000 to 2500 MCM conductors gain a water-tight, mechanically tough sleeve that withstands -67 to 230 °F. Installers needing a thinner wall, a lower shrink temperature than 250 °F, or a shorter cut length should choose a different conduit.

3:1 Shrink Ratio Decides Fit

The 4.5 in to 1.5 in transition is the single measure that determines whether this conduit will seal your specific cable bundle. Verify the conductor diameter falls inside that range before ordering.

Questions about this item

How thick is the wall after the 3M HDT-4500 shrinks to its final 1.5 in diameter?

The wall measures 0.17 in once the tubing has fully recovered to its 1.5 in inside diameter.

Will the adhesive-lined polyolefin withstand continuous exposure at the upper end of its -67 to 230 °F range?

The material is rated for continuous operation up to 230 °F and the adhesive remains stable throughout that range.

What minimum wire size must already be in place for this 4.5 in supplied diameter to shrink down effectively?

The tubing is designed for cables from 1000 MCM up to 2500 MCM, so the conductor must fall within that range.
