3M FP301-3/32-TO-1/2-ASSRTED-5 – Frequently Asked Questions
1) What sizes are included in the 3M FP-301 assorted heat shrink tubing kit?
The FP-301 assorted kit covers tubing from 3/32 inch up to 1/2 inch, so one kit handles a spread of wire and cable diameters instead of stocking separate rolls per size. Order model FP301-3/32-TO-1/2-ASSRTED-5.
2) Is FP-301 single wall or dual wall tubing, and does it seal out moisture?
FP-301 is single wall, thin flexible polyolefin. It insulates and mechanically protects wire, splices and terminations, but single wall tubing has no adhesive liner, so it is not an encapsulating moisture seal. For a direct-burial or wet-location splice you want an adhesive-lined dual wall tubing instead.
3) How long is each piece of tubing in the 3M FP-301 kit?
Each tubing size comes in a 48 inch length, which you cut down on the bench or in the truck to whatever the termination needs. That matters for service work: one stick covers several splices rather than forcing you back to a spool.
4) Will an assorted heat shrink kit work for a service truck, or should I buy tubing by the roll?
For a truck or a maintenance cart, the assortment is the right call: 3/32 through 1/2 in one box covers most control wire through small cable terminations without carrying several spools. If you repeat the same size all day on one production job, individual rolls of that single diameter are the more economical stock.
5) Do I need a heat gun for 3M FP-301 heat shrink tubing?
You need a heat source. FP-301 is shrink-to-fit polyolefin, so it only conforms to the wire once heat is applied; a heat gun is the normal tool on electrical work. The tubing itself is supplied as cut lengths with no clamps or connectors, so terminals and splice connectors are ordered separately.
6) Can I use 3M FP-301 tubing for color coding and wire identification?
Yes, wire identification and color coding are listed uses for FP-301, alongside splice and termination insulation and bundling. Cut short bands from the 48 inch lengths and shrink them at the conductor ends.
7) What is the 3M part number and UPC for the FP-301 assorted size kit?
The 3M part number is FP301-3/32-TO-1/2-ASSRTED-5 in the FP-301 series, 48 inch assorted lengths.
