  • 100 ft continuous spool lets you cut exact lengths
  • Shrinks at 212 °F with 900 V dielectric strength

1/16" Heat-Shrink Tubing for Fine Wiring

3M FP301 thin-wall polyolefin tubing shrinks 2:1 to insulate and protect wires from 28 AWG to 26 AWG. The 100 ft spool supplies continuous length for cutting exact pieces. Black colour aids visual identification in dense harnesses. Flame-retardant material resists acids, alkalis and common solvents.

Sustained Thermal and Chemical Behaviour

Operating range spans -67 °F to 275 °F, so insulation remains stable during prolonged engine-bay heat or industrial-process temperatures. Dielectric strength of 900 V holds under continuous electrical stress. Solvent and chemical resistance prevents degradation when exposed to oils, fuels or cleaning agents over time. Minimum shrink temperature is 212 °F for reliable recovery.

Pre-Installation Checks

Verify conductor diameter fits within the 0.06 in expanded inner diameter and the 0.03 in recovered inner diameter. Confirm the 0.02 in recovered wall thickness meets your insulation thickness requirement. Ensure a heat source capable of reaching at least 212 °F is available for proper shrinking. No adhesive lining means mechanical strain relief must be planned separately.

Questions about this item

How much heat does the 3M FP301 1/16" tubing need before it starts to shrink around my wires?

The tubing begins to shrink at 212 degrees Fahrenheit, so a standard heat gun or even a hair dryer on high will activate it.

What wire gauges can I actually fit inside the 0.06 inch inner diameter before shrinking?

The manufacturer specifies 28 AWG to 26 AWG wire sizes for this 1/16 inch tubing.

Will the 3M FP301 tubing become brittle if I leave it on a harness that sees 275 degrees Fahrenheit continuously?

The polyolefin material is rated for a continuous temperature range up to 275 degrees Fahrenheit without losing flexibility or flame-retardant properties.
