so this has happened 3 or 4 times now, my pressurized co2 tubing has just "fallen off" the 1/8 to barb connection coming out of my solenoid. theres a big noise and then all the co2 leaks out, the first time it happened i lost all of my co2 and i realized that i had the wrong sized barb connection a 1/4 connection. So, i bought the new barb for the correct size for the tubing, 1/8" and it came off last night. I know this time it is the right size, im not sure what to do im using gla tubing so i think its legit. help! :icon_cry:

Does the solenoid get very warm? It's possible that the tubing is stretching and coming loose when it gets warm. I am using clippard co2 tubing which is a little stiffer and doesn't come loose.

Hose clamp, definitely. They make them down to very small diameters. Just go to your local hardware store with a sample of your CO2 tubing, and tell them you need a hose clamp for it.

The temperature of the solenoid shouldn't be an issue. I am set up with solenoids and don't have that issue.

Has this happened several times in a row?

Do you have a check valve installed? Is it installed in the right direction? Could an improperly installed check valve be causing enough back pressure to build up and pop the tubing off of the hose barb?

yes this has happened several times now, i do have a clippard brass check valve installed after the inline fabco, and the arrow on it points towards the inline bubble counter towards the tank. Is this the correct way for it to be in or do i have it in backwards? this would explain so much, like how water gets past it and into the fabco......

ok here is a picture of my setup,

first picture is the parker solenoid to a 1/8 inch barb connection thats where the tubing keeps falling off,

i have an inline fabco nv 55 along with a clippard brass check valve, and inline bubble counter,

i tried two other barb sizes besides the 1/8", a 1/4" and a 3/16" both of those were too big for the tubing.
