Default Double Manifold, closing 1 need valve.

Ok so I am taking down one of my tanks that is connected to a double manifold co2 regulator, I cant close the needle valve if I'm correct all the way because its like jamming a needle onto a flat surface... So how do I stop Co2 from going into one bubble counter on a double manifold?

Assuming there is a bit of extra tubing that could be lost? I go for simple and close the end of a bit of tubing that comes out of the needle valve. If I have the picture right, this forms a plug on the output of the needle valve.
This is easier than expected on lots of tubing I use. Turn off the tank valve, cut the tubing somewhere a few inches away from the needle valve. Use a lighter or match to set the tube end on fire, then use pliers to mash the burning end together. As it cools the end is likely to be sealed. Not a big fire, Co2 doesn't burn and it works quick and easy but od have things lined up and head on straight so the pliers are handy?
The other needle valve will likely need to be reset as all the flow will be going to one rather than two outlets.

Yes that would make a nice plug but then there are some that use odd threads? any way to take it to the store and actually see what screws in well? Small parts work like this tends to drive me crazy if I don't actually take everything to see it really does fit. There were always too many different threads, etc. but now that we have so much more import, I've totally lost it for guesses on what will fit at times.
Is this one where the bubble counters screw down into the top of the manifold? That might make it possible to take the bubble counter off fairly easy, take that to the store and find what it fit, then go for the bolt??? Some stores have the board for sizing fittings like faucet adapters that are hard to eyeball.
Better than leaving a pigtail of tubing if the right one can be found.

Unfortunately, this would be from online. Rural location.

Got a better look at your setup on the other post and different way to close it off came up. Before going too far on getter a bolt to fit, maybe look at taking the top off the bubble counter and then cutting a "washer" out of some rubber type thing. I'm thinking of the washers like we use between the CGA320 and the reg? Only one without a hole in the middle and then sandwich it in between the end and the bubble counter? Since it is low pressure at that point, it might not have to be very special. Something like a piece of leather or most anything that compresses to form a "cork"?
Brain storm or brain strain? Not much difference, huh?
I lived in the "suburbs" of Blue Eye, Mo for a few years and know what it means to not have a store on every corner. We had to call ahead to see if the Dairy Queen was open.

Think I may just go with the SS bolts to be safe, but I do like your DIY idea. I thank you for your help on this, others I'm sure benefited from this to.

Thanks much,
Nate
