Twelve four-foot lengths of black adhesive-lined heat-shrink tubing, 3/16 inch diameter

3M

3M EPS200 3/16" Black Shrink Tubing 4ft PK12

SKU CH-SF9Y-EDRMK

Adhesive-lined polyolefin tubing shrinks 2:1 to seal and protect 20–18 AWG wires, supplied in twelve four-foot black lengths

  • Adhesive lining seals out moisture and contaminants
  • 2:1 shrink ratio fits 20–18 AWG wires securely
  • Flame-retardant polyolefin resists abrasion, acid and alkali
  • Operates from –67 °F to 230 °F in harsh environments
  • Twelve 4-foot pieces supply multiple repair jobs

3M EPS200 3/16" Shrink Tubing 12 Pack

This 3M EPS200 heat shrink tubing is a polyolefin conduit with an adhesive lining. It is designed for automotive and general electrical insulation tasks where a 2:1 shrink ratio is required. The tubing fits wire sizes from 20 AWG to 18 AWG. It is sold as a pack of 12 individual pieces, each measuring 4 ft in length.

Adhesive Lined Polyolefin Changes Sealing

The adhesive lining melts during the shrinking process to create a moisture resistant seal around the connection. This provides abrasion resistance and protection against acids and alkalis. The material is flame retardant and remains flexible across a temperature range of -67 Degrees to 230 Degrees F. The black colour allows for standard identification in wiring looms.

Heat Gun Install Needs 250 Degrees F Minimum

A heat gun or similar tool must reach at least 250 Degrees F to activate the shrink and adhesive flow. The inner diameter shrinks from 0.19 in to 0.09 in with a final wall thickness of 0.03 in. Overheating can damage the tubing or the underlying wire insulation. Users needing larger diameters or different shrink ratios cannot use this specific size.

Questions about this item

Does the adhesive-lined polyolefin degrade after repeated heat cycles?

The tubing is rated for a continuous temperature range of -67°F to 230°F and shrinks at 250°F, so normal operating heat will not break down the adhesive.

What stops the tubing from shrinking further during a long, hot installation?

The 2:1 shrink ratio is complete once the inner diameter reaches 0.09 in and the wall thickness stabilises at 0.03 in; it will not shrink beyond that point.

How warm does the tubing get when it is left on a live 18 AWG circuit all day?

The polyolefin is flame-retardant and rated to 230°F, well above the heat produced by 18 AWG to 20 AWG wires under normal load.
