3M 7000132422 Medium-wall Heat Shrink Cable Sleeve Mdt

Product Description

The 3M 7000132422 is a medium-wall, flame-retardant heat shrinkable cable sleeve from the MDT series, engineered for durable cable protection in demanding environments. Constructed from split-resistant cross-linked polyolefin with a factory-applied thermoplastic adhesive and sealant liner, this sleeve delivers reliable mechanical and environmental protection once heat is applied. Each sleeve measures 48 inches in length and weighs approximately 2.02 pounds per unit. The sealant liner softens during heating, bonds to underlying cable surfaces, and fills small voids to create a tight environmental seal. Licensed electricians and cable technicians install these sleeves for splices, terminations, and cable bundling applications where moisture, corrosion, and abrasion resistance are required.

This sleeve is suited for residential and commercial electrical and low-voltage cable protection applications, including wire bundling, splice protection, and mechanical shielding in environments exposed to chemicals, moisture, and abrasion. The MDT series offers greater flexibility compared to heavy-wall HDT sleeves, making it well-suited for installations requiring conformability. The 48-inch unprinted lengths are sized by expanded inside diameter and ordered accordingly based on the cable or bundle diameter at the installation point.

Key Features

• Medium-wall construction made from cross-linked polyolefin for split resistance and flexibility
• Flame-retardant material suitable for code-sensitive electrical installations
• Factory-applied thermoplastic adhesive and sealant liner bonds and seals during heat application
• Provides resistance to abrasion, corrosion, and chemical exposure
• Fast-shrinking profile simplifies installation with minimal tooling or specialized training
• 48-inch unprinted lengths allow field cutting to required size

Compatibility

Designed as an OEM-style protective sleeve for electrical cables, wire bundles, and splice points requiring medium-wall heat shrink protection with an integrated sealant liner. Select the size based on the expanded inside diameter equivalent to the cable or bundle being covered.

Installation Notes

Installation is performed by licensed electricians or qualified cable technicians. De-energize all circuits before applying heat shrink sleeves to any live cable assembly. Use an appropriate heat gun or torch to apply uniform heat, working from the center of the sleeve outward to avoid trapping air. Do not overheat, as excessive temperature can damage the cable jacket or degrade the sealant material.
