3M 7100066097 Heat Shrink Tubing EPS300 1/8 in 48 in Black

Product Description

The 3M 7100066097 is a thin-wall heat shrink tubing designed for environmental protection and electrical insulation in wiring and cable assemblies. Sold as individual 48-inch sticks, this tubing carries the EPS-300 designation and is supplied in black. It suits applications where a low-profile shrink sleeve is needed to seal, protect, and insulate conductor terminations, splices, and bundled wire runs. Electricians and wiring harness technicians reach for this product when a clean, durable insulation layer is required without adding significant bulk to the assembly. At 1/8-inch nominal diameter, it is sized for small-gauge wire work and fine conductor bundles.

This tubing is a fit for residential, commercial, and light industrial electrical work. Typical install scenarios include protecting wire splices in control panels, insulating terminal connections on low-voltage wiring, and bundling small-diameter conductors in HVAC controls, appliance wiring, and instrumentation. The 48-inch stick length allows technicians to cut segments to the exact length needed on the job, reducing waste and improving workflow on repetitive termination tasks.

Key Features

• EPS-300 thin-wall construction provides environmental protection and electrical insulation
• 1/8-inch nominal diameter targets small-gauge wire and fine conductor bundles
• 48-inch stick length allows field cutting to any required segment length
• Black color for standard insulation identification and UV-light resistance typical of this product type
• Lightweight at 0.03 pounds per stick, minimizing added mass to finished assemblies

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeve suitable for small-diameter wire terminations, splices, and conductor bundles in electrical and low-voltage control wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified wiring technicians. De-energize all circuits before applying heat shrink to any conductor or termination. Apply heat evenly using a heat gun set to the appropriate temperature range for EPS-300 material — avoid open flame, which can scorch or unevenly shrink the tubing. Follow applicable NEC guidelines for insulation ratings and conductor protection requirements in the specific installation environment.
