3M 7000132419 Medium-wall Heat Shrink Cable Sleeve Mdt

Product Description

The 3M 7000132419 is a medium-wall, heat-shrinkable cable sleeve from the MDT series, designed for protecting wire and cable assemblies in demanding environments. Constructed from split-resistant, cross-linked polyolefin with flame-retardant properties, this sleeve delivers reliable mechanical and environmental protection. Each sleeve measures 48 inches in length and ships in cases of 20. A factory-applied thermoplastic adhesive and sealant is built into the inner wall. During installation, heat softens this sealant, causing it to bond to the underlying surface and fill small voids for a secure, moisture-resistant seal. Licensed electricians and cable installers working in industrial, commercial, or utility applications regularly specify this sleeve where long-term environmental durability is required.

The MDT cable sleeve suits applications where cables or conductors are exposed to abrasion, corrosion, chemicals, or environmental contamination. Its medium-wall construction offers greater flexibility than heavy-wall alternatives such as the HDT series, making it a practical choice for installations requiring conformability around irregular or bundled cables. The sleeve is unprinted and designed to fit based on the expanded inside diameter of the cable assembly being protected. It is used across electrical, industrial, and utility field work wherever a durable, heat-shrinkable protective jacket is needed.

Key Features

• Cross-linked polyolefin construction resists splitting under mechanical stress
• Flame-retardant material meets requirements for fire-sensitive environments
• Factory-applied inner adhesive and sealant bonds to surfaces and fills voids during shrink
• 48-inch length provides substantial coverage per sleeve
• Greater flexibility than heavy-wall HDT sleeves for easier routing around complex geometries
• Fast-shrinking design reduces labor time and requires minimal training for installation

Compatibility

Designed as an OEM-style protective sleeve for wire and cable assemblies requiring medium-wall heat-shrink protection with an integrated adhesive and sealant layer. Select the sleeve size based on the expanded inside diameter of the cable or bundle being covered.

Installation Notes

Installation is performed by licensed electricians or qualified cable technicians. De-energize all circuits completely before applying any heat-shrink sleeve to a cable assembly. Use an appropriate heat gun or torch rated for heat-shrink work, applying even heat along the sleeve to allow uniform shrinkage and full activation of the inner sealant. Avoid overheating any single area, as uneven heating can result in poor adhesion or damage to the underlying insulation.
