Best waterproof connectors

[codprawn]

Being lazy and wanting a quick fix I need to connect my new bilge pump - it's exactly the same as the old one. I can't find where the wires join so I was thinking of just snipping the wires in the transom well and splicing on the new ones. What is the best way to make these waterproof? Heatshrink or bullet connectors(yuk) or what?

I will do a proper job when the boat is out of the water - the way the weather is here I prob only have about 1/2 an hour without getting soaked to do it in.

try a through connecter crimp and some of this

You can always wrap it in self amalgamating tape
not sure on the spelling

I did think of both those - but haven't got any - will have to order some anyway - always useful.

Hi Codprawn,

I used a cone shaped connector, you twist the wires together and push then in the cone then crimp it. The cone is made of plastic so the outer is waterproof and after i'd crimped it i filled the top of the cone with silicone.

Codders, get a length of silicon tube used for fuel line on models. Slide a length about 25-30mm onto the cable where it is to be joined. It's very grippy, you'll need to work it along the cable. Tin both cable ends to be joined with solder. Snip them off at 45º and about 2mm long. Re-tin one of them with a wee blob of solder. Bring the 45º ends together and flow the blob of solder to make the join. Wait until it cools and then slide the silicon tube over the joint to make the seal. Totally watertight.

A couple of these http://www.go2marine.com/product.do?no=16129F should do the trick. I usually overcoat with adhesive lined shrink tubing, just to be sure.

As I happen to have some silicone tubing handy I will do that for now - great idea!!! I will try to get some of the Adhesive Lined Heat Shrink for when I do it later - thanks all.

We use solder and glue lined heatshrink - 2 layers for anything that may be submerged in regular use.

Codders,

Try Farnell catalogue and get some Raychem crimps, they are a crimp that can be heatshrunk on (also has hotmelt glue inside) then slip some glue lined heat shrink over this or alternatively PM me with your address and Ill send you what you need (please include sizes i.e the conductor and the dia of insulation)

Reason being it isnt cheap and they like you to buy lots!
