3M FP301 Thin-Wall Heat Shrink

3M FP301 is a thin-wall polyolefin tube that shrinks 2:1 when heated. The clear sleeve fits wire gauges from 20 AWG to 18 AWG and comes in a 100 ft cut-to-length spool. It is aimed at technicians and hobbyists who need reliable insulation and strain relief for small-gauge wiring.

Replaces tape and loose sleeving

The tubing replaces electrical tape or loose braided sleeving when a permanent, professional seal is required. The jump is worth it when the installation must resist abrasion, solvents, acids and alkalis while remaining flexible after shrinking. Adhesive-lined tubing is not supplied, so environmental sealing needs a separate product.

100 ft spool for bench stock

The 100 ft length provides enough material for many small-gauge repairs and prototype builds. It comfortably handles 20 AWG to 18 AWG conductors with a pre-shrink diameter of .19 in and a recovered diameter of .09 in. Wall thickness after shrinking is .02 in, and dielectric strength is rated at 900 V. The tube runs out at the minimum shrink temperature of 212 °F or beyond the 275 °F upper operating limit.

Questions about this item

What wire gauge range does the 3/16 in tubing cover?

It fits 20 AWG to 18 AWG wire, shrinking from 0.19 in to 0.09 in inner diameter.

What minimum temperature is required to shrink the tubing?

Apply at least 212 Degrees F; the material shrinks at a 2:1 ratio to a 0.02 in wall thickness.

Does the clear tubing contain an adhesive liner for sealing?

No, this thin-wall polyolefin tube is not adhesive-lined; it relies on friction fit after shrinking.
