3M FP301 1/2 in Clear Heat Shrink Tubing

This thin-wall polyolefin tubing provides flexible, flame-retardant insulation for wires from 6 AWG to 1 AWG. It comes on a 100 ft spool in clear colour for easy visual inspection. The material resists acids, alkalis and common solvents. It operates across a temperature range of -67 to 275 degrees F.

Shrink ratio and dimensions

The tubing has a 2:1 shrink ratio, reducing from .5 in inside diameter to .25 in after heating. Minimum shrink temperature is 212 degrees F. Wall thickness after shrinking is .03 in. Dielectric strength is rated at 600 V. These figures determine whether the tubing fits your specific wire gauge and insulation needs.

Suited for general wire protection

This product suits technicians and hobbyists needing versatile, non-adhesive insulation for splicing, bundling or strain relief. It is not for buyers who need adhesive-lined tubing for environmental sealing. It is not for applications requiring a higher shrink ratio or thicker wall for heavy mechanical protection.

Questions about this item

What does the 2:1 shrink ratio mean once the tubing is heated on a wire?

The tubing shrinks to half its original diameter, so the 0.5 in inside diameter becomes 0.25 in after heating, gripping the wire tightly.

What does the 600 V dielectric strength cap in practice?

It means the material can withstand up to 600 volts without electrical breakdown, suitable for low-voltage wiring insulation.

What size wire bundle fits inside the 0.5 in tubing before shrinking?

The tubing is rated for use with wire sizes from 6 AWG to 1 AWG, so bundles within that range will fit before heat is applied.
