3M Heavy Wall Heat Shrink Cable Sleeve, Black Polyolefin

The 3M Heavy Wall Heat Shrink Cable Sleeve is built for professionals who need dependable protection over cable splices, terminations, and multi-conductor connections. Constructed from rugged black polyolefin, this heavy wall sleeve is available across a range of sizes — from an expanded diameter of 0.65" (recovering to 0.24") in a 6" length, to an 0.88" expanded diameter (recovering to 0.4") in a 6" length, up to a 2" diameter sleeve in a 12" length. This range lets installers match sleeve dimensions to the cable joint, splice, tap, or connector body being protected. The heavy wall build offers greater mechanical protection than thin-wall alternatives, and because the sleeve is heat-activated, it shrinks down tightly around irregular shapes to form a close, long-term protective fit for electrical and cable assemblies.

Key Features

  • Sleeve Diameter & Length Range: Available from 0.65" expanded / 0.24" recovered diameter x 6" length, to 0.88" expanded / 0.4" recovered diameter x 6" length, up to 2" diameter x 12" length, so the right sleeve size can be matched to the connection being covered.
  • Heavy Wall Construction: A thick-wall polyolefin design delivers greater mechanical strength, crush resistance, and long-term durability compared to standard thin-wall heat shrink tubing.
  • Polyolefin Material: Flexible, chemical- and abrasion-resistant polyolefin construction conforms tightly around cable splices, connectors, and irregular shapes once shrunk.
  • Heat-Activated Recovery: Installs with a standard heat gun or torch, shrinking down from its expanded diameter to a snug recovered fit for a secure, weather-resistant seal.
  • Black Jacket: Black polyolefin finish provides a uniform, professional appearance while standing up to everyday jobsite handling.
  • Versatile Coverage: Longer lengths are sized to fully enclose cable joints, taps, and connector bodies in a single continuous sleeve, reducing the need for multiple wraps of tape.

3M ITCSN-0800-6IN-BLACK – Frequently Asked Questions

1) How do I pick the right size 3M heavy wall heat shrink sleeve for my cable splice?
Size by the largest point you have to slide the sleeve over, then check that the recovered diameter is smaller than the cable you are sealing onto. The 3M heavy wall polyolefin sleeves come in three sizes: 0.65 inch expanded recovering to 0.24 inch in a 6 inch length (ITCSN-0800-6IN-BLACK), 0.88 inch expanded recovering to 0.4 inch in a 6 inch length (ITCSN-1100-6-BLACK), and 2 inch diameter in a 12 inch length (ITCSN-2000-12IN-BLACK). The expanded figure has to clear the connector body or crimp; the recovered figure is what grips the jacket.
2) Will a 6 inch sleeve be long enough to cover an inline cable splice?
It depends how much of the connector you need buried. A 6 inch sleeve has to span the crimp or connector body plus enough overlap onto the jacket at both ends, so for a compact butt splice on small conductors it works; for a longer tap, joint, or multi-conductor connector body, go to the 2 inch diameter x 12 inch sleeve, which is sized to enclose a joint in one continuous piece rather than multiple wraps.
3) What is the difference between heavy wall and thin wall heat shrink tubing?
Wall thickness, and what it survives. The thick wall polyolefin build on these 3M sleeves gives more mechanical strength, crush resistance, and long-term durability than standard thin wall tubing. Thin wall is fine for marking and light insulation on conductors inside a panel; heavy wall is what you want over a splice that is pulled through a raceway, buried in an enclosure entry, or exposed to abrasion and handling.
4) Can I install these 3M sleeves with a propane torch, or do I need a heat gun?
Either. The sleeve is heat activated and installs with a standard heat gun or a torch, shrinking from its expanded diameter down onto the cable. Work the heat evenly around the circumference and from the center outward so air is pushed out rather than trapped under the recovered sleeve.
5) Will heavy wall heat shrink seal over an irregular shape like a connector or a tap?
That is the point of the heavy wall polyolefin. Once heated it recovers tightly around irregular shapes, conforming over splices, connector bodies, and taps for a close, weather-resistant fit. Just confirm the expanded diameter clears the widest part of the body before you slide it on, since you cannot open it up again once it has recovered.
6) Is this heat shrink sleeve suitable for marine or outdoor cable?
Yes. The black polyolefin is chemical and abrasion resistant and the line is used for industrial and marine cable protection, enclosure and panel cable entry protection, and strain relief on cable assemblies. Black also holds up to jobsite handling and keeps a uniform appearance across a run of splices.
7) Does the 3M heavy wall cable sleeve come in any color other than black?
Black only. Every size in the line is black polyolefin, so if you are color coding phases or circuits you will need to mark the sleeve externally or use a separate identification product. For splice protection where appearance just needs to be consistent across the job, black is standard.
8) What is the full diameter range of the 3M heavy wall heat shrink cable sleeves?
The sleeves span 0.65 inch to 2 inch, with recovered diameters from 0.24 inch to 0.4 inch on the smaller sizes and lengths of 6 to 12 inches. That covers everything from small conductor butt splices up to a 2 inch body needing a foot of coverage.
