Is wire shrink wrap waterproof?

Hi,

Need to extend my motor wires and the join is going to be outside my compartment.

Was planning to use multiple layers of wire shrink tube like this to make the join waterproof. Is this going to be sufficient? Or should I look at some kind of waterproof connectors?

There is shrink tube with glue inside, that should be waterproof.

liquid tape the join and then shrink tube

You can also put silicone on the junction of the wires and once dry you put your heat-shrinkable sheath

Thanks for the info.

Had thought about using something like this so I can detach the mast from the board but they area a bit bulky

Here’s how i successfully used waterproof connectors that can also be disconnected anytime. See my build for details Florida Build - PM Based

Thanks @sunrise305 I had actually also been looking in the last few days at a virtually identical item on ebay

Good to know you had some success with these type of connectors

Cheers,

@Riwi XT150: The other way around uses a threaded shell that needs some adjustments.
