3M 7000133601 Heat Shrink Tubing 3/16 in 48 in Black

Product Description

The 3M 7000133601 is a multi-wall, semi-rigid heat shrink tubing designed for durable wire and cable protection in electrical and electronic applications. Built from co-extruded, selectively cross-linked polyolefin, it features a 2.5:1 shrink ratio and an integral meltable inner wall that flows and bonds around irregularities during heat application. Each stick measures 48 inches in length with a 3/16-inch recovered diameter. The construction creates a sealed, mechanically robust sleeve suited for harsh-environment wiring work. Licensed electricians, panel technicians, and field service professionals working with bundled conductors, terminals, and splice points are the primary installers.

This tubing is used in residential, commercial, and industrial electrical installations where moisture ingress, vibration, or mechanical abrasion is a concern. The meltable inner wall makes it well suited for connector backshells, wire splices, and terminations that require an environmental seal. It is commonly applied in control panels, equipment wiring harnesses, and field-service repair of multi-conductor cables. Each stick format supports bench work and field use alike.

Key Features

• 2.5:1 shrink ratio provides reliable coverage over connectors and splices
• Co-extruded semi-rigid polyolefin construction resists abrasion and mechanical stress
• Integral meltable inner wall flows into voids for an environmental seal upon heat application
• 48-inch stick length suits both bench and field installation workflows
• Black color supports standard wire identification and UV light blocking

Compatibility

Designed as an OEM-style replacement and standard-use heat shrink tubing for electrical wire protection applications requiring a 3/16-inch recovered diameter multi-wall sleeve.

Installation Notes

Installation is performed by qualified electricians or electronics technicians following applicable NEC guidelines. De-energize all circuits before applying tubing to conductors, terminals, or splices. Use a heat gun calibrated to the tubing manufacturer's recommended temperature range and apply heat evenly along the length of the sleeve to achieve full shrink and inner-wall flow. Avoid open-flame heat sources, which can cause uneven shrink, charring, or damage to adjacent insulation.
