3M 7000031598 – Frequently Asked Questions

1) What is the difference between the two 3M FP-301 kits, the assortment and the black?
Both are FP-301 thin-wall polyolefin heat shrink kits, and the difference is color content only. One kit is an assorted-color pack (MPN 7000031588) for wire marking and phase or circuit identification, the other is all black (MPN 7000031598) for general harnessing and repair where color coding isn't needed. Specs are otherwise the same tubing: 2:1 shrink ratio, flexible polyolefin, 48 in (1.22 m) sticks.
2) How much will 3M FP-301 tubing shrink down, and how do I pick a size for my wire?
FP-301 has a 2:1 shrink ratio, so each piece recovers to roughly half its supplied inside diameter. Pick a size that slides over the largest thing it has to pass (connector body, splice, backshell) and still recovers tight on the smallest diameter in the run. The kit format gives you multiple diameters in 48 in (1.22 m) sticks, so you cut to length rather than working from pre-cut pieces.
3) What temperature do I need to shrink FP-301, and can a heat gun on low do it?
Minimum shrink temperature is 100 C (212 F), so a standard electrical heat gun handles it easily. Keep the gun moving and work from the center out to avoid trapping air. Once installed, the tubing operates continuously from -67 F to 275 F (-55 C to 135 C).
4) Is 3M FP-301 heat shrink rated for 600 volt circuits?
Yes. The FP-301 tubing is rated for applications up to 600V, with a dielectric strength of 900 V/mil. That covers normal building branch circuits, control wiring, and motor leads. It is a single-wall thin-wall product, not adhesive-lined, so it insulates and jackets but does not seal against moisture on its own.
5) Is the clear FP-301 tubing flame retardant like the colors?
No. Flame retardancy applies to all colors except clear. In colors, FP-301 meets AMS-DTL-23053/5 Class 1; clear falls under Class 2 and is not flame retardant. If your spec or facility requires flame-retardant tubing, use a colored piece, not clear.
6) Does FP-301 meet military spec requirements for wire harness work?
It meets SAE AS23053/5 Class 1 (AMS-DTL-23053/5, Class 1), which is the spec commonly called out on military and aerospace harness drawings for thin-wall flexible polyolefin. It is also UL Listed under File E-39100, CSA Certified, and passes the UL 224 all-tubing flame test.
7) Will this heat shrink corrode copper terminals or tinned leads?
No. FP-301 is a non-corrosive flexible polyolefin, so it can go directly over bare copper, tinned leads, and crimp terminals without attacking the metal. That is why it is used for wire bundling and component packaging as well as splice covering.
8) Is FP-301 tough enough for tubing that gets flexed or abraded in a panel or on equipment?
Tensile strength is 2400 psi, and the material is flexible polyolefin, so it takes bending and handling in a panel or on moving equipment without cracking. 3M lists it for split-resistant covering and wire harnessing. For direct mechanical abuse or fuel and oil immersion, a heavy-wall or adhesive-lined tubing is the better choice; this is a thin-wall single-wall product.
9) Is 3M FP-301 RoHS compliant and made in the USA?
Both. FP-301 is RoHS 2011/65/EU compliant without exemption, and it is manufactured in the United States, which matters on government and institutional orders with domestic-source requirements.
10) Can I use this heat shrink on motor leads or near hot equipment?
Continuous operating range is -55 C to +135 C (-67 F to 275 F), so it holds up on motor leads, engine compartment wiring, and equipment that runs warm, and it stays serviceable in cold-storage or outdoor winter conditions at the low end. Above 275 F you need a higher-temperature tubing such as a fluoropolymer.
11) How is the FP-301 kit packaged for an MRO stockroom?
Tubing comes as 48 in (1.22 m) sticks in kit form, and the kit is sold 5 kits per case. The assorted-color kit is the usual stockroom choice because one box covers multiple diameters and identification colors for a shop cart or service van.
