3:1 Ratio Heat Shrinkable Tubing

Professional-Grade Polyolefin Tubing With or Without Adhesive Lining

Low Price Guarantee

HS3-0063FT   

What's special about this flame retardant heat shrink?

  • 3:1 heat shrink ratio allows it to fit over the end of a large connector, but will still shrink down enough to seal to the cable
  • Choose between standard and dual wall (adhesive lined) styles
  • Optional “dual wall” heat shrink has adhesive lining that melts when heat is applied and re-solidifies after shrinking, creating a snug, watertight bond between the tubing and cable
  • Available in several colors, making it easy to match your wiring scheme or color-code cables and connectors
  • Can be purchased by the foot or in bulk spools, so you get as much as you need
  • Click for More Features
Passes UL VW-1 Flame TestRoHS Compliant

Our 3:1 heat shrink tubing is an effective way to insulate cables, provide extra strain relief, or professionally finish the ends of wire harnesses. The over-expanded tubing slides easily over bulky connectors, and then shrinks down to 33% of its original diameter to fit snugly around both connectors and the wires attached to them. For an extra tight bond, choose adhesive heat shrink, which efficiently and attractively terminates cable snakes, and prevents fraying along the cut edges of expandable braided sleeving.

  • High shrink ratio helps to seal and protect awkwardly-shaped objects with varying diameters
  • Flame retardant and heat resistant to protect cables against damage from high temperatures
  • Adhesive lining (included in the "dual wall" option) creates a tight seal between tubing and wires, so that the tubing won't shift or slide off
  • Less than 10% shrinkage in the axial (lengthwise) direction, so you can better estimate the length of material you will need
  • Passes UL VW-1, CSA OFT, -F- MARK for safety specifications

3:1 Heat Shrink is ROHS (Restriction of Hazardous Substances) Compliant

Adhesive Lined Tubing

The adhesive version of our 3:1 heat shrink features "dual-wall" design, which is made up of an outer polyolefin (heat shrink) tube lined with a interior coating of heat-activated adhesive. During application, as the outer tubing shrinks, the inner layer melts, flows, and then resets when cooled, helping the tubing to achieve a snug, moisture-resistant fit around wire harnesses, cables and connectors. We recommend it for applications that require strain relief, watertight seals, or wire color-coding (for example, to help identify positive and negative battery connections).

LG heat shrinkable and non-shrinkable tubing products do not contain the compound Di (2-ethylhexyl) phthalate commonly referred to as DEHP.

In addition, LG heat shrinkable and non-shrinkable tubing products do not contain PFOS (perfluoroctane sulfonate), PFOA (perfluorocanoic acid) or Tinuvin 320.

 

 

Limiting Oxygen Index (LOI)
The ratio of how much oxygen - as compared to other gases - needs to be present in the air surrounding a particular material in order for that material to burn. The fact that Earth's normal atmospheric air contains around 21% oxygen is used a reference point when materials are classified into burn categories that are based on Limiting Oxygen Index. Substances that are combustible in air containing less than 21% oxygen are considered flammable, while those that burn in the range of anything greater than 21% but less than 28% are typically labeled "slow burning". Any material with an LOI that exceeds 28% is classified as self-extinguishing.

In the table below, you'll find a list of polymers commonly found in our heat shrink tubing and braided sleeving products, along with their LOIs and the burn categories each falls into.


MATERIAL ALTERNATE NAME LOI CATEGORY
ECTFE (Ethylene chlorotrifluoroethylene) Halar 64% Self Extinguishing
Nomex N/A 28% Slow Burning
Nylon 6:6 N/A Ranges fron 24-29% Slow Burning to Self Extinguishing
PET (Polyethylene Terephthalate) Mylar (film), Dacron (fiber) Ranges from 21-34% Slow Burning to Self Extinguishing
Polyethylene (PE) N/A 17% Flammable
Polypropylene (PP) polythene (in the UK) 17% Flammable
Polytetrafluoroethylene (PTFE) Teflon 95% Self Extinguishing
Polyvinyl Chloride (PVC) N/A Ranges from 45-49% Self Extinguishing

A:Answers

  • - Thank you for your question. This would depend on your application, environment, temperature, amongst many other factors, hence the FDA would not even bother testing products like these.

          Comments about 3:1 HEAT SHRINK 1/4 INCH:

          I primarily use this for live sound applications. On XLR cables, color defines the length.

          On the mixer end of the snake I pair 4 of the connectors connectors with color. This makes plugging in the snake a snap.

          If I had a wish it would have a low-tac adhesive inside to help small pieces stay in place.

          The variety of colors gives lots of options!

          I honestly don't have anything bad to say about this.

          The product seems ok but I found that shrinking needs a lot of heat and I do not think that a 3:1 ratio is exact. I do have 2:1 and I found not much difference.

            Used the standard clear 3:1 shrink over stainless weave to cover wires on my Harley and looks great. Wanted to use the dual wall adhesive clear for a particular location but it has a dirty yellow tint. Decided to try it in the hopes that the adhesive would clear once melted but it actually did the opposite. Looked awful! Picture old dirty yellowed cables and its very difficult to remove and not very flexable. I will say its tough so if you don't care about looks it will do the job.

                  I used it to bind together like cables in my home stereo install. I like the 3:1 shrink tubing because it can go over all but the largest of connectors and it shrinks enough to make a tight bundle. It shrinks evenly and works well.
