3M FP301 Single Wall Heat Shrink Tubing with Header Label
3M FP301 Single Wall (Thin) Heat Shrink Tubing with Header Label is a flexible polyolefin heat shrink product designed to deliver reliable insulation and mechanical protection for a wide range of wire and cable applications. This black tubing is supplied in a 48-Inch stick length and is available in 3/16", 1/2", and 3/4" trade sizes, so you can select the diameter that best fits the wire or cable bundle at hand and cut each stick to the exact length needed for the job. The included header label helps electricians and contractors quickly identify and organize the product on the shelf, in the truck, or in inventory. When heat is applied, the thin-wall polyolefin material shrinks down to create a tight, low-profile seal over wires, splices, and cable terminations while retaining flexibility after installation.
Key Features
- Trade Size: Available in 3/16", 1/2", and 3/4" diameters to fit a range of standard wire and cable bundles for a consistent, snug shrink-down fit.
- Durable Construction: Flexible polyolefin material provides reliable insulation and abrasion resistance over the life of the installation.
- Length: Supplied in a 48-Inch stick length that can be cut down to the exact size needed for each application, minimizing waste.
- Header Label: Integrated header label allows for fast identification, sorting, and inventory management on the shelf or in the field.
- Color: Black finish supports standard color-coding practices for wire and cable identification and organization.
- Single Wall (Thin) Design: Lightweight thin-wall construction shrinks tightly for a low-profile finish over splices, terminations, and cable bundles.
- Flexible After Shrinking: Polyolefin material remains flexible once shrunk, reducing stress on wires and connection points.

3M FP301-3/16-48IN-BLACK-HDR – Frequently Asked Questions
1) What trade sizes does the 3M FP301 black heat shrink tubing come in?
Three trade sizes: 3/16 inch, 1/2 inch, and 3/4 inch, all in black polyolefin and all supplied as 48 inch sticks. Pick the size by the diameter of the wire or bundle you are covering before shrinking, then cut the stick to the length you need. Part numbers are FP301-3/16-48IN-BLACK-HDR, FP301-1/2-48-BLACK-HDR, and FP301-3/4-48IN-BLACK-HDR.
2) Single wall versus dual wall heat shrink: which should I use for an outdoor splice?
FP301 is single wall (thin wall) polyolefin. It insulates and resists abrasion, and stays flexible after shrinking, but it carries no adhesive liner, so it does not seal moisture out of a joint. For a buried, wet-location, or direct-weather splice you want an adhesive-lined dual wall tubing or a sealed splice kit instead. Use FP301 for dry-location insulation, splice and termination coverage, harness protection, and bundling.
3) Is FP301 sold on a spool or in cut sticks?
FP301 black tubing here is supplied as 48 inch sticks, not spooled reels. For a truck stock or shop bin that is usually what you want: cut each piece to length off the stick and there is no waste left on a partial reel. Each stick ships with a header label for shelf and inventory identification.
4) Can I use FP301 heat shrink over crimped terminals and butt splices in a panel?
Yes. Thin-wall FP301 shrinks down tight and low profile over splices, lugs, and terminations, which matters in a crowded gutter or panel where bulky tubing fights the bend radius. It stays flexible after shrinking, so it does not stiffen the conductor at the crimp. Size it so the unshrunk tubing slides over the connector body before you apply heat.
5) What size FP301 do I need for a multi-conductor bundle versus a single wire?
Go by the outside diameter of what you are covering while the tubing is still expanded. The 3/16 inch size suits single small-gauge conductors and individual splices, 1/2 inch handles larger single conductors and small harness runs, and 3/4 inch is the one for multi-conductor bundles and bigger terminations. All three are the same black polyolefin in 48 inch sticks, so a contractor stocking all three covers most wire management on a job without reordering.
6) Will black FP301 work for color-coded wire identification?
The tubing is black only in these sizes, so it works as the neutral or ground-side marker and as a general jacket, but it will not give you a color-coded phase scheme on its own. If you are marking phases, pair it with printed wire markers or order colored tubing for the color legs.
7) Do I need a heat gun, or will a lighter shrink FP301 tubing?
Use a controlled heat source such as an electrical heat gun. The polyolefin shrinks with applied heat and an open flame scorches the tubing and the conductor insulation, which leaves you with a brittle or split jacket instead of a clean seal. Work the heat evenly around the tubing from the center outward.
