3M EPS300 Adhesive Lined Heat Shrink Tube Kit 42pc Black Red

SKU CH-84VR-1Q3T0

Adhesive-lined polyolefin heat-shrink kit with 42 pieces in black and red, 3:1 shrink ratio, acid and alkali resistant, rated to 700 V dielectric strength, operating from -67 °F to 230 °F

  • Adhesive-lined tubing seals out moisture and corrosion
  • 42-piece kit covers 1/2 in, 3/4 in and 1 in diameters
  • 3:1 shrink ratio fits wire sizes from 6 AWG to 500 MCM
  • Operates from -67 °F to 230 °F for harsh environments
  • 700 V dielectric strength insulates high-voltage connections

Heat-shrink kit for wire repair

The 3M EPS300 kit contains 42 adhesive-lined polyolefin tubes in black and red. It covers wire sizes from 6 AWG to 500 MCM with three inner diameters before shrinking. The thin-wall material is acid and alkali resistant for general electrical work.

Shrink ratio and temperature limits

A 3:1 shrink ratio reduces each tube to one-third of its original diameter when heated. The operating range spans -67 °F to 230 °F, so the tubing stays flexible in cold environments and stable under normal load heat. Dielectric strength is rated at 700 V for insulation confidence.

Simple installation with common tools

Cut the required 6 in length, slide it over the joint and apply heat until the adhesive flows and the wall shrinks tight. The kit supplies 12 pieces of 3/4 in, 24 pieces of 1/2 in and 6 pieces of 1 in diameters. Builders needing larger diameters or dual-wall construction will need a different assortment.

Questions about this item

How do I decide between the 12 pieces of 3/4 in, 24 pieces of 1/2 in, and 6 pieces of 1 in tubing in this kit?

The kit provides 42 pieces total: 24 pieces of 1/2 in for smaller wires, 12 pieces of 3/4 in for mid-range, and 6 pieces of 1 in for larger cables up to 500 MCM.

What does the 700 V dielectric strength mean when the tubing is installed on a live circuit?

The 700 V dielectric strength rating indicates the maximum voltage the polyolefin wall can withstand after shrinking without electrical breakdown.

How does the 3:1 shrink ratio limit the range of wire diameters I can cover with each size?

Each tube shrinks to one-third of its original inner diameter, so the 1/2 in size covers wires down to roughly 1/6 in, the 3/4 in down to 1/4 in, and the 1 in down to 1/3 in.
