Co2 Bubble Counter Problem


The tubing on my bubble counter sometimes falls off as the Co2 exits the unit to return to the tank. When it falls off it drips water onto my tank stand even with my check valve. See pictures. The last picture ( Close Up) is where the tubing sometimes falls off.

How do I stop this from happening?

If I over tighten, then it just falls off instantly...

Is there an o-ring placed between the brass fitting that connects the tubing to the bubble counter?

+1. Check to make sure you have not misplaced your O-ring. It is required to achieve a tight seal.

I figured out what the problem was. I had the o ring underneath the tube.

So, I took the owing off the brass bubble counter and put it on the outside of the tube. lol stupid mistake.

Thanks guys.

If you have water from the tank flowing back through the check valve and getting your stuff wet, the check valve is bad and needs to be replaced.

Glad you solved the tube popping off problem.

Just a heads up: The o-ring is meant to be placed where the bubble counter screws onto the needle valve. See the link below.

I saw that back when it was posted as well; to be honest, I don't see a difference now, I have placed the O-ring in both locations, and it seems to be fine either way.

You will find a variety of O-rings at the hardware store, but you may not be able to find the appropriately sized one.
