DIN valve with water

[David Novo]

This weekend, before a dive one of my DIN valves was leaking through the small hole that some valves have.

I reattached the first stage and the problem was solved so took it for another 2 dives without any issue. After the dives, I noticed that there was water in the valve.
I am assuming the sea water did not go in as the tanks were pressurized. Is this a fair assumption or they may be a corrosion problem?

The problem with that specific first stage persists (leak when testing dry) so I assume it is the o-ring.

I'm assuming the tank was pressurized at 500+ PSI the whole time? a little bit of water around the threads isn't something I'd be worried about.

Definitely more than 35 bar

thats just the weep hole working as intended

Was just cleaning some gunk out of the valve of a recently purchased used tank and found that it has weep hole. At first glance it looked like a thread deep in the valve face was broken but it lines up directly with the weep hole. I had to do a search to find out if this was a thing because I had never noticed a weep hole in any the valves I had previously used. Glad this thread was available in the search result as it surely eased my mind.
