High quality 3:1 tubing, perfect to repair iPhone charging cable 11/15/2016
Reviewed by: Ricardo from Miami.
HS3-025-10-WT Is the perfect size and white color to repair iPhone charging cable. Small amount of soap to slide over end easier, a few seconds under the heat gun and now better than new.
Great heatshrink 9/24/2016
Reviewed by: Johnson from Texas.
These are the best heatshrink I've ever used. I was using those cheaper ones and these on from Electriduct is way more superior in quality. They are thicker, can withstand more abuse with regular use, and they can also shrink to pretty small size.

After trying several variations of tubing for our toys, this tubing did the best job. It was among the lowest prices I could find, was delivered in a reasonable time, and i working very well. I will most likely order more when we're out. Mouse Factory Toys

Perfect application 5/4/2014
Reviewed by: Jay Kissack from Algonquin, IL.
The 3:1 ratio of this heat shrink tubing is perfect for smaller gauge wire when your using solder-less connectors. This will be my choice for heat shrink tubing from now on. Everything I have ordered from Electricduct has been great and delivery is the fastest "standard shipping" I've ever experienced! I will continue to order from Electricduct!
