What's a high quality CO2 check valve?

I'm using the plastic one for air tubing, Hate it. The metal ones on Ebay don't look too good either. Where can get quality check valve for CO2 rig?

Inline check valves? I stick with plastic ones. I got some stainless steel ones from TPT seller before. Great guy but they all failed. All 3. This is why I run 3 inline in case. My plastic ones I get from the store for i dunno $2.99? Never had one fail yet. The high quality ones are made by like swagelok or clippard or some industrial gas company. Expect to pay a lot more for these but yes, they are great. But cmon, for the availability and price of plastic? Run at least 2 inline. Mine look like these:

Not those disk ones, but those probably will work as well.

I have to replace the plastics ones every couple of months. Hard to predict. If I want one that works a couple of years instead, where shall I look?

I've JBL ProFlora SafeStop on my system and work great!

I'm restart my aquarium so it stored and can't take pic of it.

If you need one I can get you NIB PM me for that

Here in Israel we enjoy European market products, most of them (to my opinion) is better than the US market products.

Best Regards,
