  • Operates from –67 °F to 275 °F with 212 °F shrink temperature

3M FP301 1/4 in 100 ft Clear Heat Shrink Tube

This 100 ft spool of 3M FP301 heat shrink tubing is made from flexible polyolefin with a 2:1 shrink ratio. It fits wire sizes from 16 AWG to 12 AWG and provides a clear, thin-wall insulation sleeve for electrical and industrial applications. The material is flame retardant and resistant to acids, alkalis and solvents. It operates across a temperature range of -67 Degrees to 275 Degrees F.

Thin-wall polyolefin replacement for tape

The tubing replaces electrical tape and thicker adhesive-lined sleeves where a slim profile and dielectric strength of 600 V are required. The jump is worth it when you need acid and alkali resistance combined with solvent resistance in a non-adhesive, flexible format that shrinks down to 0.13 in inner diameter. It suits repairs and original builds where minimal wall thickness of 0.03 in after shrinking is specified.

Cut-to-length spool installs

The spool is packaged cut to length so you pull off the exact amount needed and apply heat at a minimum of 212 Degrees F. A heat gun or torch shrinks the tube evenly; the clear colour lets you inspect the joint before and after shrinking. What usually goes wrong is uneven heating that leaves unshrunk sections or overheating that damages the underlying wire insulation.

Questions about this item

What is the inner diameter before shrinking and what wire sizes does it cover?

The tube has a 0.25 in inner diameter before shrinking and is rated for 16 AWG to 12 AWG wires.

What minimum temperature is needed to shrink the tubing and what tool is commonly used?

A minimum of 212 °F is required; a heat gun is the standard tool, and the common mistake is using a lighter which can scorch the polyolefin.

Does the tubing have an adhesive lining and how does that affect future inspection?

It is not adhesive lined, so the clear wall allows visual inspection of the splice and the tube can be cut away for rework without melting glue residue.
