Scuba Tank Valve "Snorkel" - Dip Tube

My tank valve "snorkels" i dont know what else they call them, the dip tubes that plug into the valve; anyway they keep coming undone in my tanks and rolling around in the bottom. I’m not comfortable with draining the tanks having to unscrew the tank valve to put them back seemingly after every dive... Anyone have this problem? Suggest a solution?

I believe you are referring to the scuba tank valve "dip tube". The dip tube should just screw into the tank valve. Remove the valve from the tank, turn the tank upside down to retrieve the dip tube, then use a cloth or rubber covered channel lock pliers to screw back in...not extremely tight, but snug. Then screw the valve back onto the tank and only hand tighten.

if your uncomfortable with this, theres always option 2.. bring them to the dive shop

I had this happen once. I always let my wife use that tank because it was easy to find her underwater. Very noisy! ;-) My dive shop used locktite when they screwed it back in and it has not come loose since.

I don’t think I really want to breathe in adhesive. And yes each time I go to fill them they have to empty them to get the snorkel screwed back in, and sadly every time it comes back out :(

What about plumbers joint tape?

If it’s coming undone that easily every time, I think you should just buy a whole new tank valve. A dab of locktite could be a good idea. Try the plumbers/teflon tape, but I’d be concerned about a piece coming off and restricting airflow (wouldn’t that be a case for Murphy’s Law).

My local dive shop sells rebuilt oxygen ready saddle valve for $25. and new vavles for $40. Soon you will be at that amount in repairs. I would replace the valve and would not use any material not rated for oxygen use on the tank. IMHO

Thanks for the advice, guys!

A new tank valve is due. $50 or a tank full of gas for the car. $50 just don’t go that far anymore.
