Re: [APD] CO2 systems
I searched until I found a really good plastic check valve from the
McMaster-Carr website. I used it to make a bubble counter from a
medical syringe- I siliconed it into the open end of the syringe.
Worked great -- for a few weeks. Then, like all plastic check valves
it began leaking badly. So, I installed the brass check valve I got
from Rex to back it up. I doubt any plastic check valve will endure
CO2 usage for more than a few weeks.
