3M 7100025556 Heat Shrink Thin-wall Tubing

Product Description

The 3M 7100025556 is a flexible polyolefin heat shrink thin-wall tubing sold in a small spool format. Heat shrink tubing in this class is used to insulate, protect, and bundle wire terminations and electrical connections. When heat is applied, the tubing contracts uniformly around the substrate, creating a snug, protective sleeve. Electricians, HVAC technicians, and panel builders use thin-wall polyolefin tubing for low-voltage wire harnessing, terminal insulation, and general wire management tasks on both residential and light commercial projects.

This tubing is suited for electrical and electronics applications where a lightweight, flexible insulating sleeve is needed over conductors, connectors, or splices. It is commonly installed during control wiring work on HVAC systems, electrical panel builds, and field wiring harness repairs. The polyolefin construction provides reliable dielectric insulation and resistance to common shop fluids and mild abrasion, making it a practical choice for service technicians working in the field or at the bench.

Key Features

• Flexible polyolefin construction provides lightweight insulation and resistance to mild abrasion and fluids
• Thin-wall profile allows use in space-constrained wiring layouts
• Small spool format supports bench work and field service kits
• Uniform shrink ratio ensures consistent coverage over conductors and terminals
• Sold by the foot with a minimum order quantity of 300 feet

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeve for use over wire conductors, splices, and terminal connections in electrical and low-voltage control wiring applications.

Installation Notes

Installation is performed by electricians or HVAC technicians following applicable NEC guidelines for wire insulation and termination. Always de-energize the circuit before applying heat shrink tubing to any conductor or terminal. Use a heat gun set to the appropriate temperature range for polyolefin tubing and apply heat evenly along the length of the sleeve to achieve uniform shrinkage. Do not use an open flame, as uneven heat can damage the tubing or adjacent components.
