Under-water control cable joints

mercredi 26 novembre 2014

As the title implies, I need to make a couple of low voltage connections which will be under water (up to 1.5m below the surface of our water tank). I need to fit a couple of reed float switches inside my tank and can;t do them through the wall. The two wires from each sealed switch are only about 200mm long. So I need to solder cables to them and seal the joints.

What options are available? Shrink sleeves with glue inside them are available, but the staff at the local shop couldn;t guarantee that they would be water pressure proof. I wondered about filling shrink sleeves with silicone before shrinking them.... or fitting glue-type shrink sleeves and then encase them in longer spagetti sleeves filled with epoxy, for example.

What's available for the purpose, please?
