## Questions & Answers

**Q: Air tight? Was thinking about using this to cover flare fittings on a mini-split hvac for support.**
A: Hi,

Yes, our heat shrink tubing is air tight. If you have any other questions, please feel free to send us a direct message.

**Q: what size should i get to fit (3) 10AWG wires to make an extension cord ?**
A: Depending on the type of wire and how thick the casing on the 10 gage wire.  You might get away with 3/8 but I think it would be very tight, especially if long. So be safe and use 1/2 inch..
You will b fine.  Look a the wire you are getting at its specs.  It should tell you major dia.  Add the 3 up. 2/3rds of you total will be bare minimum . But remeber if you make it to tight before shrinking.  It will be hard to slide wire through.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Working great for my boat wiring
*by A***R on April 15, 2025*

Great stuff! The 4 to 1 makes this really versatile.

### ⭐⭐⭐⭐⭐ The good stuff
*by B***T on February 23, 2025*

Shrinks up really well- I used it to hold two battery cables together for the RV. The glue does a great job of expanding to create a watertight seal between two cables.

### ⭐⭐⭐⭐⭐ great tubing
*by R***D on December 30, 2024*

This heat-shrink tubing has a good heat-activated adhesive inside of it. There is a good amount of shrink that doesn't require a crazy amount of heat. This tubing is easy to use and stays in place. Not thin walled.
