I'm looking for a mechanism I can employ so that I can pull liquid containing bottles that are upside down out of a system, fill it, put the cap (with mechanism) back on. Then be able to turn the bottle upside down and push it back into the system to allow liquid flow. I want it to not leak anything until i push it into the main unit.
Basically, a combination bulkhead+valve that where the valve is activated by connecting the bulkhead on one side.
I realized I've seen a "push to connect" bulkhead thingie like this before. My water filter in my fridge pushes in to start the water flow. How does it do this? What kind of bulkhead fitting is on it. Some pictures of it here
How does it work, presumably the water is ready to go on the other side and doesn't flow until you push in this unit which is horizontal.
