water proof wire connector

Found this on Facebook and it is heat shrink tubing with a metal connector inside that is made out of low temp solder, insert the 2 wires mesh together and heat and you wind up with a water proof electrical connectorwater proof wire connectors.PNG
 
Looks like a quick solution.
I use the screw/twist top connectors then fill with clear silicon sealant

Interesting idea, will be useful to hear if anyone tries some out......

We use them a lot on aircraft wiring repairs. We use a heat shrink gun to melt the solder and shrink the insulation.

I've also used them on the signals used on my old layout....
 
Are they also adhesive-lined? - Else how can they guarantee a waterproof seal? :think:

Is the coloured ring some kind of gasket/seal?
 
The ones I use don't have coloured rings. All our sizes are black.

The rings do shrink but the seal is done by the heat-shrink itself, which does have adhesive.

We have other in-line splices here, one of which works similar to the splice that one uses to wire in a towbar socket. However, these ones have a gel inside which makes the connection waterproof. I've used these on my railway successfully....
 
Useful to know, Giz - any idea what the ones you use are actually called, to make it easier to search for something similar online?

Thanks Giz - have been looking for them (or similar) on Rapid's site, but can't find them at the mo. Maybe they are there and I'm just searching for the wrong terms.....?

A quick question about using a heat gun for heatshrink - what temp setting do you generally use? I don't presently have a heat gun, whenever I use heatshrink I just run the side of the soldering iron tip gently over it until it has the required effect! Probably not a "recommended" way of doing it for the professionals, but it seems to work.....

I also occasionally use the side of a soldering iron for heat-shrink too! :eek:

And I also use Caroline's hairdryer too? She does know this BTW. ;)

With a heat gun, I tend to use a low setting, but if you use a high temp, it just shrinks quicker! :whew:

As the splices are transparent, it's easy to see when the solder melts and the insulation has shrunk enough. :rofl:

I'll give you a couple or three to play with next time we meet up.... :nod:

Thanks Giz!
I'm surprised that a hairdryer, used with or without permission, actually generates enough heat? What sort of temperature do you need to reach before heatshrink will start to shrink, or does it vary by size or type?

Hair dryers do get very hot! I don't think that there's much difference between Caroline's (which seems to be set to its hottest setting all the time) and a Heat Gun, apart from the fact you can put different nozzles on the gun to direct the heat better.

I've never experimented with the temp settings and looking at a comment from this linky from your favourite Rapid Electronics, it doesn't seem to be specified....
