Super Check Valve
This works really good. I had trouble under standing which way to attach them - the larger side gets attached to the line going to CO2 diffuser. A arrow or something may be nice. Also push the CO2 tube well into this check valve for it to work properly.

Check Valve
The check Valve has given out in less than 2 months. Water is reaching my regulator, but since the bubble counter itself has a check Valve I am safe for now. Not worth it for 20$.

Heavy duty valve.
Very nice and extremely heavy duty. This guy is literally heavy, and GLA tubing is perfect fit. Super happy with this one.

Heavy duty and always working.
This is my new favorite check valve for my reactor. Its stainless steel and the seals always working.

Excellent product
For those who are wondering, the LARGE METAL END points towards the DIFFUSER. With that being said, within 5 minutes of messaging customer service, they sent a response to answer my question. Product is heavy and well built compared to other (even other brand name) check valves. 5 star.

Last check valve you will ever need.
Check valves have always been a pain in the ass for me until this one arrived. Its heavy, and it feels substantial and everyday its always working. Instead of me freaking because water had passed the check valve. Not with this bad boy, I just ordered 3 more just because.

Almost Perfect
Compared to other check valves, the weight alone shows that is a solid and high quality product. I gave it 4/5 stars simply due to there is an engraving that makes no sense to me that symbolizes which direction to connect it. At the very least, the company could add a picture to the purchase product online indicating which direction to face it. For anyone else wondering the same, the silver part faces the CO2 diffuser.

The best co2 check valve.
Every check valve fails, but this freaking thing is working flawlessly.

Definitely my favorite check valve from now on.
Check valves are a pain in my ass because Im always buying them every year. I came across this bad boy and I feel like this is the one. Its heavy, and only works with real co2 tubing. GLA actually is the only provider of US made co2 tubing, and it fits like a glove to this check valve. It has a super low cracking pressure and is always rock solid day in and day out. I cant say the same for all my other shit box check valves. This sucka is the jam pony!

Best check valve Ive used.
I hate check valves because I feel Im always replacing them. Ive been using this valve for a few weeks now and its been more than perfect. Its very rock solid and heavy and you can tell the internals are well made just by design. This is a super valve indeed.
