3M EPS300 3/16in 48in Black 12 PCS Heat Shrink Tubing
Adhesive-lined polyolefin tubing shrinks 3:1 to seal and protect 20–18 AWG wires, 48 in lengths in a 12-piece pack
- Adhesive-lined tubing seals out moisture and contaminants
- 3:1 shrink ratio covers 20 to 18 AWG wires
- Thin-wall polyolefin resists abrasion, acids and alkalis
- Flame-retardant material rated from -67 °F to 230 °F
- Twelve 48-inch black pieces ready for individual use
Thin-Wall Heat Shrink Tubing
This 3M EPS300 tubing is designed for electrical insulation and strain relief on small-gauge wiring. Each of the twelve pieces measures four feet long before shrinking. The polyolefin material carries a flexible, thin-wall construction with an inner adhesive lining that bonds when heated. It suits electricians and technicians who need a moisture-resistant seal on 20 AWG to 18 AWG conductors.
3:1 Shrink Ratio and Wire Range
The tubing starts with an inside diameter of .19 in and shrinks to .06 in, providing a 3:1 ratio that accommodates the stated wire sizes with room for connectors. After full recovery the wall thickness is .04 in, delivering abrasion and chemical resistance without adding bulk. It will not fit larger cables or bundle multiple thick wires; the maximum recovered diameter limits use to the specified gauge range.
Thermal and Environmental Limits
Minimum shrink temperature is 250 Degrees F, and the continuous operating range spans -67 Degrees to 230 Degrees F. The material is flame retardant and resists acids and alkalis, making it suitable for harsh environments within that thermal window. Applications exceeding 230 Degrees F or requiring a higher shrink temperature fall outside the product's rated performance.

Questions about this item
Will the 3:1 shrink ratio on this 0.19 in tubing cover my existing 20 AWG to 18 AWG wires?
Yes, the tubing shrinks from 0.19 in down to 0.06 in, which matches the 20 AWG to 18 AWG range listed for this product.
How can I confirm the adhesive liner has activated after heating the 48 in pieces?
Heat until the tubing shrinks tightly and adhesive flows visibly at the ends; the minimum shrink temperature is 250 Degrees F.
Does the pack of 12 black pieces include a heat gun or cutting tool?
No, the box contains only the 12 individual 48 in lengths of adhesive-lined polyolefin tubing; tools are sold separately.
