3M FP301 Series Black Polyolefin Thin-Wall Heat Shrink Tubing

The 3M FP301 Series is a thin-wall heat shrink tubing engineered for insulating and protecting wire splices, cable ends, terminals, and connector bodies in commercial, industrial, and MRO electrical work. Constructed from flexible polyolefin material in a black finish, this tubing is available in diameters ranging from 3/16-Inch to 1-1/2-Inch, supplied in 48-Inch stick lengths that can be cut to custom segments on site. When heat is applied with a heat gun or torch, the polyolefin material shrinks tightly around the substrate to deliver a low-profile, mechanically secure covering that helps guard against abrasion, moisture intrusion, and mechanical stress. This diameter range makes the FP301 Series a practical stock item for electricians, panel builders, and maintenance technicians who need reliable insulation across a wide variety of wire and cable sizes.

Key Features

  • Diameter Range: Available from 3/16-Inch to 1-1/2-Inch to match wire and cable sizes from small conductors to larger cable bundles.
  • Stick Length: Supplied in 48-Inch lengths that can be field-cut to the exact segment needed for each splice or termination.
  • Durable Construction: Flexible polyolefin material resists cracking and provides a reliable, heat-activated shrink fit over time.
  • Thin-Wall Design: A slim wall profile shrinks tightly around wires, cables, and connector bodies without adding unnecessary bulk.
  • Field-Cuttable Length: The 48-Inch stick can be trimmed to the exact segment length needed for each application.
  • Finish: Black color provides a clean, uniform appearance and standard color coding for wire and cable identification.
  • Versatile Coverage: Suitable for bundling multiple conductors together or insulating a single larger cable or connector body, depending on the diameter selected.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Wire and Cable Splice Insulation
  • Cable Bundling and Strain Relief
  • Connector and Terminal Protection
  • Motor Lead and Terminal Insulation
  • Electrical and Industrial Wire Harnessing

3M FP301-1-1/2-48IN-BLACK – Frequently Asked Questions

1) What diameters does the 3M FP301 black heat shrink tubing come in?
The FP301 black polyolefin tubing spans 3/16-Inch through 1-1/2-Inch diameter. Ordering splits into two choices: a 3/16-Inch to 1-Inch group (MPN FP301-3/16-TO-1-BLACK) covering the smaller conductor sizes, and a single 1-1/2-Inch size (MPN FP301-1-1/2-48IN-BLACK) for larger cable and connector bodies. Pick the diameter so the unshrunk tubing slides over the splice or connector before heat is applied.
2) Is thin-wall heat shrink like FP301 the right choice, or do I need a heavy-wall adhesive-lined sleeve?
FP301 is a thin-wall, non-lined polyolefin tubing. The slim wall shrinks tightly over wires, cables, and connector bodies without adding bulk, which is what you want inside a panel, in a wire harness, or where several sleeved conductors have to sit together in a tray or raceway. If your job needs a sealed, gasketed moisture barrier on a direct-buried or submerged splice, that calls for a heavy-wall adhesive-lined sleeve instead, not a thin-wall product.
3) Does 3M FP301 heat shrink come on a spool or in cut sticks?
Sticks, not spool. FP301 black tubing is supplied in 48-Inch lengths that you cut on site to the segment each splice or termination needs. For a service van or panel shop, that means one stick covers multiple terminations without a dispenser or reel.
4) How do you shrink FP301 tubing in the field?
Heat gun or torch. Slide the FP301 sleeve over the splice, terminal, or connector body first, then apply heat and the polyolefin shrinks down tight around the substrate for a low-profile covering that resists abrasion, moisture intrusion, and mechanical stress. No adhesive or crimping step is involved.
5) Can FP301 tubing bundle several conductors together, or only cover one wire?
Both, and it depends entirely on the diameter you order. The smaller sizes in the 3/16-Inch to 1-Inch range suit single conductors and terminals; the 1-1/2-Inch size takes a larger single cable or a bundle of conductors gathered together for harnessing and strain relief.
6) What color is 3M FP301 tubing available in?
Black only. Every FP301 size covered here is black polyolefin, which keeps a uniform look across splices and serves as the standard neutral color on wire and cable work. If your job spec calls for color-coded phase identification, you need colored tubing rather than this black stock.
7) Will FP301 heat shrink work on motor leads and terminal lugs?
Yes. Motor lead and terminal insulation is one of the listed uses for the FP301 polyolefin tubing, along with splice insulation, connector and terminal protection, and wire harnessing in commercial, industrial, and MRO work. Choose a diameter that slips over the lug body before shrinking, since the sleeve has to clear the widest point of the termination.
