Shrink tubes come in 2:1, 3:1 and 4:1 ratios. The type used in electronics, like this one, are 2:1. Usually the material is a little better than the minimum specified, so you will get srink ratios better than 2:1, and always less than 3:1.
Man you can but by god it can take a long time.. My lighter ran out of gas when i was doing the terminals on my battery and the missus came up with this idea.. Never again.. 5 seconds with a lighter.. about 5 minutes each with the blow dryer at full ball.
Would have to be a darn good hair dryer. I usually use the side of my soldering iron, barely get close to it, and it doesnt hurt to barely touch it. A lighter works really well but leaves black marks on the red. The Soldering iron leaves them pretty! =)
One way to get the hair dryer option to work is to make a cone on the nozzle so that you get a concentrated blast of hot air. WARNING: This will also cause your blwo dryer to run hotter than it's supposed to. It could be damaged or catch fire.
If the connection is exposed and you can move the wire and/or piece, a simple candle works. Start a good distance above the candle and see if it starts to shrink ** slowly lower until it does shrink, then rotate it.
I have a little torch that runs of
Did you all realize that you get this heatshrink for free (100pcnt savings) as a combo prize?
5 thumbs up!
Great shrink tubing at a very low price. The 4 mm size works great for covering splices on motor and ESC wires and for covering the solder connection to gold bullet connectors. I ordered both red and black. It shrinks easily and looks and works just like the expensive products from local sources.
