inline co2 check valve

[stadelman]

I want to T off of my co2 line before it gets to a secondary regulator and manifold. This would be a high pressure (30 psi) line used for force carbing.

I've got a stainless T to do this. I'm wondering if I need a check valve. This side of the system is always going to have a higher pressure. Do you think I need a check valve here?

Anybody know of an appropriate in line check valve? I'd like to have something with 1/4" barbs on both ends.

I found this thing...

Which would actually be perfect. I just don't want to pay $31 with shipping.

Great find... thank you!

Just some questions. Are you regulating the line out of the CO2 cylinder then off to two more regulators, one for dispensing (~10Psi for example) and then on efor force carbonating (30 Psi)?

Or

Just one main high pressure line out of the CO2 bottle (800 Psi capable) to the two purpose serving regulators (10Psi and 30Psi)?

You can see where I am going. You need to be sure you have lines rated for full cylinder pressure prior to the regualtors. FYI.

I get what you're saying. I think I'm good to go.

I have a dual gauge regulator on the tank. The pressure coming out of that regulator is 30 psi. It currently feeds a secondary regulator. The secondary regulator has two gauges. One of the gauges just has a gas line hooked up to it. The other gauge feeds a 4 way manifold.

So this particular inline regulator would go between the primary and secondary regulators. It's pressure would be determined by the setting on the primary regulator. It will always be the highest pressure available since I need to feed the secondary.

I ended up finding a pretty good deal ($12.99) on a tee with an inline check valve. This will be cleaner than the tee to check valve that I was thinking about.

Here's the web page on that in case anyone is interested-

Nice stuff. Sounds like you are good to go. Take care!
