Heat shrink tubing size

[macordani]

Hi guys easy question I hope. After I install bullet connectors on my hobbywing esc/motor, what size heat shrink tubing to use? I see many online saying 3/16, but just wanted to verify before ordering. Also see 1/8 is a common size. Thanks.

3/16 sounds about right.

Heatshrink comes in different shrink ratios. You can still find cheap and nasty 2x in some places but the most common will be 3x or 4x. This means that it will shrink to a third or a quarter of the original size respectively. Of course this is the rating so allow a bit of optimism there. I use 4x mostly as it gives more margin for error.

One of the things I look for in the best heat shrink tubing is reliability. That’s why I like the Ginsco Heat Shrink Tubing. Because wherever I install them, they don’t loosen. So, even if I put them in my car’s engine bay, they wouldn’t melt and break, even if they’re exposed to scorching temperatures.

I usually get a pack with a bunch of sizes, I recently got some from harbor freight and they suck.

That is all I have to offer on this topic
