CO2 Check Valve

I think it is a pressure thing. The ones designed for co2 are industrial grade too which would be more reliable than the hobby grade plastic ones you usually find at the LFS. Reeeeeeeeeaaaaaaallly bad things can happen if check valves fail in an industrial setting.

Dennerle makes a CO2 check valve made of plastic. It doesn't seem to be listed on the Ocean Aquatics website but that's where I got mine. Call Wendell and ask for one.

It looks like this:

Thanx. I saw that one on Marine Depot as well and was considering it also. I'll get in touch with OA. Thanx for all the replies.

Thanx for that link, Tony. OA doesn't carry it (or any other Canadian outfit, it seems, for that matter). I placed an order with Aqua Cave. We'll see how it goes.

Cheers,
