Question Electrical connectors for underwater

[PietroT]

Negative.

The water will (nearly) instantly wick/penetrate back through the cabling and flood your light head and battery canister

I have never tried unplugging underwater and those connectors are not meant for wet activities.
For me it works because I do not need any plugging/unplugging underwater.

In my configuration, I have a battery only for the heating system and I do not need to plug/unplug underwater.

Moreover, from a pure mechanical perspective, it might be hard with dry gloves to screw/unscrew the locking ring and have the two parts matching.

Kindly also consider that the EO cord permits the plugging/unplugging underwater because of the distance between the two poles and of the associated resistance.

With the connectors I am using such distance (and the consequent resistance path) is much shorter.

I have often wondered if some of the newer automotive connectors would work reliably. I have seen them with dual o rings and pretty snug fits; once where the wires exit are properly potted...

Haven't gotten that far in my tinkering, but it is something I consider when I see them.

If E/O cable has been penetrated through rubber then is there cotton thick fibre thread which soak water and swells like feminine hygiene tampons, thereby preventing water from penetrating further down the cable.

Just this cheap light from China. Been using it for ages now for sump diving. Works fine but battery runs out after about 4 hours and I'd like to get that up to 12. It doesn't have to be wet pluggable. Its actual time underwater on any given trip would be no more than 1 hour and usually no deeper than 15-20m
