What check valve do you guys suggest?

I think Nilocg sells them on here.....

I got mine from ADA but I do not notice a difference between the two I just mentioned.

I used some of these: http://www.usplastic.com/catalog/item.aspx?itemid=23369&catid=489&clickid=searchresults They continued to work after over a year in a CO2 system, so the plastic they use is probably resistant to CO2. Most plastic check valves made for air systems don't last long with CO2.

I had okay luck with the regular airline ones but recently had one start leaking water down the line whenever the CO2 was off. Got some of the polypropylene/Viton check valves here and they work great.

Thanks for the link, I am going to buy one, soon as I find out what size hose I can get.
