3M FP301 Heat Shrink Tubing 1/16

This 3M FP301 heat shrink tubing is designed for electrical insulation and wire management in automotive and industrial applications. The pack contains twenty-five individual black pieces each measuring forty-eight inches in length. It suits technicians and hobbyists who need reliable protection for small-gauge wiring.

2:1 Shrink Ratio and Temperature Limits

The tubing offers a 2:1 shrink ratio, reducing from an inner diameter of 0.06 inches to 0.03 inches with a recovered wall thickness of 0.02 inches. It is rated for continuous use from minus sixty-seven to two hundred seventy-five degrees Fahrenheit and requires a minimum shrink temperature of two hundred twelve degrees Fahrenheit. The polyolefin material is flame retardant and resistant to acids, alkalis and solvents.

Wire Gauge and Voltage Compatibility

Verify that your wires fall within the twenty-eight to twenty-six AWG range before ordering. The dielectric strength is rated at six hundred volts, so confirm this meets your circuit requirements. Note that this tubing is not adhesive lined, so it relies on friction fit alone for sealing.

Questions about this item

Which diameter fits my 28 AWG to 26 AWG wires?

The tube has a 0.06 in inside diameter before shrinking and 0.03 in after, matching the 28 AWG to 26 AWG range.

What does the 2:1 shrink ratio mean once the tube is heated?

It halves the diameter, so a 0.06 in tube becomes 0.03 in with a 0.02 in wall, sealing the wire.

What minimum temperature activates the 2:1 shrink?

The polyolefin tubing begins to shrink at 212 °F and operates from -67 °F to 275 °F.
