Here is a picture of the Equinox waterproof headphones connector for all those interested. I found the pic searching the web it is from a foreign website.View attachment 1509029 If anybody can find this connector I would like to make a Equinox to CTX headphone adapter. website showed a 3year warranty also.
That seal design does not look reliable ...it looks like a face seal. If the connector loosens over time (expansion and contraction due to temperature changes going in and out of the water), the seal will leak. I'm not sire I see ANY o-ring at all in there.
I'll be using silicone on those threads or modifying the plug in my lathe to accept an o-ring around the barrel of the connector.
From what I've read, the connector itself (the jack) is sealed.. so even without a plug in the connector, the machine will not get water inside it, although shorting the connector in salt water would no doubt be BAD for the machine.

Youre going to do what?
It doesnt need an oring, do you see that rubber connector that holds the plug? Thats your sealing surface. You want to put an oring on the plug.... how is that going to work? The plug screws into the fitting, if there is an oring anywhere in that mix its only going to end up as chewed rubber. That headphone plug is waterproof, even if water got in, its not going to harm the detector. Lastly, you are most likely going to be using waterproof headphones if using this in the water, so why the worry about the dustplug?
Is that an o-ring down in the opening? It looks like it.
