Does something like this exist?

Does something like this exist? I was thinking more along the lines of air hose quick-connect fittings but you get the idea.

I'm looking to add two ports to a medical oxygen gas bottle from only one hole. One "siphon" at the bottom of the tank, and a port at the top. A 1lb propane bottle would be ideal too if you guys had any ideas for a similar connection.

I welcome any ideas. I need a pressurized cylinder for a filtration test unit. Pressure will be under 100psi.

You might need to do a quick drawing and scan it or take a picture of it to post it. Your description doesn't make a lot of sense.

My initial thought was that you may need to use a manifold, but after re-reading your description, well, it doesn't make a lot of sense, so I'm not sure that it would be a good solution.

 

[LightningEngineer]

Hmm. The picture didn't post the first time. How's that?

If I'm reading this right you want to be able to pull gas and liquid out of one tank? I know they have that setup on dewar tanks with co2. Maybe that will help you with your search. But I would just call your local gas distributor and see if they can do anything for you.

Buy a refrigerant recovery tank, they have liquid and vapor ports.

That helps a little bit more. But still need to clarify; are you trying to pressurize from one port and then dispense via the pressurization from the other port?

That drawing you show basically shows the inside of a spray paint can, except with a method of re-pressurizing.

If that's the right idea, then I'd say install a ball valve downstream of both outlets. Open one to fill/pressurize and close. Open the other ball valve to activate the pressurized stream/siphon.

The problem is that the refrigerant recovery tanks are far too big. I'm planning to use a small medical oxygen tank. Long and narrow is ideal for this application. (Filter)

The plan is to use it like a filter. A stream of air will come in through the bottom and out the top or vice versa.

Yep! I've been reading that NGT and NPT are sort of interchangeable. I wonder if it will fit the cylinder and everything!

Venturi siphon? your trying to use pressurized air to siphon a liquid right?

No. This is just for an air filter. The bottle will be filled with a filter media. and I want to just pass air through it from the bottom to the top. It will be high pressure.

but depending on pressure, you might want to use hard pipe
tube line through
comp to pipe adapter
teee(air out the side)
******
tank fitting
tubing line extends to near bottom of tank(air enters tank)

air in---=T={------ }
.............L..air out...
