Help - CO2 Leak
I finished the setup of my pressurized CO2 system today. All was working well for about 6 hours... until a fast leak occurred between the tank and regulator. I was lucky I was right there to turn off the tank.
I have it turned off for the night until I can keep a close eye on it during the day.
It is a 5lb tank, the room my tank is in is 5000 cubic feet.
In theory that would be about 16ppm if I did my math right of additional CO2 to the room. Still not fun to hear 800 psi of CO2 leaking into the room.
Is there a better option than a nylon seal?
Is that reliable and I just need to torque down the connection better next time?
Any help is greatly appreciated!
Do not worry too much about the amount of CO2 that leaked out into your room.
When you remove the regulator from the CO2 cylinder, each time, you must use a new nylon washer. Screwing the regulator onto the cylinder compresses the nylon washer, forming a tight seal. Compressed/used washers cannot be used again since they will not form a tight seal.
In any case, make sure you use a new nylon washer, tighten the nut by hand, and then take a suitably sized wrench to it and really tighten it.
Following this, I have never had a leak between the CO2 nut and the cylinder (other parts notwithstanding ;))
Thanks! Looking to get a permaseal as well.
I've never used perma-seals, mainly because of their cost (~$8 or so to get one).
Whenever I go get my cylinder refilled, I just ask for some nylon washers, and the technician is more than happy to give me a few each time. I'm slowly building up my supply :)
