Check Valve ??

[ElCid79]

I like to force carbonate, I would really like to get a check valve for my CO2 line. Do any of you know a good one?

Thanks in advance!

Also, by check valve, I mean the proper definition. One that allows air through one way, but nothing through the other way.

My manifold has these. They're a little pricey, but cheaper than the regulator I ruined way back when using those duckbill style check valves.

I'm also not a fan of the duckbill style found in so many of the shut off valves with an integral check valve. I use these super cheap in line ball style check valves- http://www.usplastic.com/catalog/item.aspx?itemid=24234&catid=489
