User questions & answers

Question:	Does each single color have same quantity? If not, how many white tubes in each size? Thanks
Answer:	No. These come in a box with dividers, and each section is the same size and contains more or less only one size of the tubing. So there are way more of the tiny tubing sizes and relatively few of the large ones. In the box I got the large ones were only black or white. I recall the 6 mm (which is what I used first) had one red but the rest were B&W. The tiny ones came in several colors, mostly black, green, blue, yellow as I recall. I would not expect another box to have the same exact counts as mine did, but perhaps the trend toward B&W in the large tubes is a real one.
Question:	What’s the size for shoes lace? I’m trying to shorten it
Answer:	I totally depends on the size of the lace. Laces for dress shoes are much smaller than, say, basketball shoe laces.
Question:	I am looking for several colors for the same diameters. How are there 532 pieces distributed? (it's not clear in the product description
Answer:	The is too long to type, but the larger ones are black, red and white; the smaller ones are all the colors (red, white, black, green, blue, yellow). Actually, they are really varied.
Question:	does this work on 14 gauge bare copper wires
Answer:	Yes but each piece is about two inches long. The batches are different sizes from very small on up . I was disappointed because of how short they are cut.

User questions & answers

Question:	Can I put these tubing on my tools to insulate for electrical work
Answer:	...which electrical? Automotive ? 12 volt range? Go for it. ...home wiring? 120-240 volts? Should be safe enough, however one does not know what the dielectric strength of the heat shrink is. Back Muppet Labs and break out the test gear, Beeker! ..residential power lines/h.v. transmission lines? Really? Use the approved tools. Don't reinvent the wheel.
Question:	CAn it be used for 12 awg or 10 awgg electrical cable
Answer:	Of course, I bought this set cuz I needed a heat shrink tube that was large enough to fit over my true 4AWG of OFC power & ground wire for my 3500watt amp & the largest 13mm pieces were just large enough to fit on my 4AWG & since I ran 10AWG for my speaker wire I can absolutely assure that this set has plenty of sizes that would fit perfectly for 10 & 12AWG Sized wire. Hope this helps
Question:	Can the tubing be cut in half lengthwise to get it over wiring which has a plug already attached, and still be heat Shrank
Answer:	I'd suggest just cutting the cord near where you are trying to repair, sliding the tube on one end of the cut, then splice the wires, slide the tube over the splice and the original damaged area, and shrink it.
Question:	Can the be shrunk with a hair blow dryer
Answer:	We went over it lightly with a long lighter to shrink it. a heat gun would work on high. Hair dryer doesn't get hot enough.

• 3:1 SHRINK RATIO - Recovers to 1/3 of its original diameter, and makes a tight seal. Eliminates the problem of 2:1 tubing not shrinking tight enough.

User questions & answers

Question:	Do the wires have to be soldered first before using the heat shrink material
Answer:	Thank you for reaching out. No, they don't. First you strip the wire and insert into splice barrel, then you crimp using the tool for heat shrink connectors, finally apply the heat, using the heat gun, while rotating the connector.
Question:	Are these tubes encapsulating
Answer:	Not sure exactly what you want to know. They do have a glue that went you heat to shrink the tube it melts and seals both ends. These tubs also stay slightly stiff after shrinking to provide extra strengh to the splice. I have used some shrink wrap tubes that are veey soft so the joint is ot protected from physical damage.

User questions & answers

Question:	Can you use solid wire too
Answer:	Sure
Question:	What is the amperage rating when rated at 240V
Answer:	Depends more on the wire size, but I would think less than the wire itself unless you mechanically twist the joint, too. Solder as the primary conductor in the joint isn't the best if the joint is likely to get heated by the current.
Question:	Do you crimp these or just twist the wires together and heat shrink them? if no crimping, how strong is it compared to crimping and heat shrinking
Answer:	You will just need to twist the wires together and heat shrink them. Solder inside the connector will melt and bond the wires together. The connection is almost as strong as crimping and heat shrinking. When heat is applied, polyolefin tubing reduces in size and adhesive flows inside the insulation, creating a strong seal
Question:	What temp do I use on the heat gun
Answer:	Low flame

User questions & answers

Question:	Will they work with 14 gauge wire
Answer:	Yes I will work for a range of wire gauges from 24g to 8g
Question:	Are these still flexable after shrinking
Answer:	After heat shrinking there is very minimal flex.
Question:	I'm looking for a heat gun or hot air gun to work with it, does anyone know the brand of "amtake" heat gun which can variable temperature control
Answer:	Honestly, a bic lighter works the best. Just be sure to hold it a couple inches away and don't stay in one spot too long to avoid melting or bubbling. It's how I learned when I was a kid and really never even heard of using a heat gun until recently.
Question:	Safe for exterior use (solar powered fountain pump
Answer:	In my opinion these fall into what I would call "light duty". If you need some that are exposed to weather and sunlight I would look for "marine grade".

User questions & answers

Question:	Between this 2:1 heat shrink and the 3:1 adhesive heat shrink, which better to use for damaged usb-c or lightning cables
Answer:	Wow....good question. I think that the adhesive stuff would work better, as well as the higher shrink ratio.
Question:	Can this be used in place of electrical tape
Answer:	Yes but, it cannot be split open. For instance, if an electrical cord's insulation is damaged, the plug would need to be temporarily removed for the heat shrink tubing to be slid over the cord. Tip: Avoid open flame heat. A low cost heat gun (around $10 usd) is great for occasional usage.
Question:	are the 2 smallest sizes really that small? 1mm and 2mm? That is too small for any project wires
Answer:	Yes they are that small. 01.0 and 02.0. Checking between these and a Commercial Electric 20-18AWG heat shrink tube the 01.0 and 02.0 are in between. The 01.0 tubes are perfect for 22AWG Arduino jumper wires.
Question:	what are the inner diameter sizes
Answer:	They vary greatly. There’s a selection of many sizes
