CO2 Brass Check Valve Information



Protect your expensive CO2 equipment from counter flow by using the CO2 Brass Check Valve from Pet Store. This tiny check valve is made from the finest quality brass manufactured by German Air Pressure Systems. The check valve's purpose is to ensure that the flow of water is only in one direction. A counter flow of water will be harmful to your CO2 regulator and cylinders. This happens when a pressurized Kalkreaktor strongly pushes the saltwater backwards. A check valve is therefore an important gadget to ensure that the flow stays in the same direction and thus protect your CO2 system.

The CO2 Brass Check Valve has earned the reputation of being the only qualified brand that is reliable and effective. It is strong and durable to take in even food-grade liquids. It is also easy to install. It is mounted inline and the tubing is soaked in warm water so that the valve can be easily attached. It is compatible with 1/8 airline tubing that is CO2 resistant and can also take 4/6 mm ID/OD tubes. This check valve is ideal to be used only in CO2 systems that are pressurized. With this check valve around, you can be sure that the big investment you spent in your CO2 system is ensured.

These are the highest quality industrial-grade Brass Check Valve from German Air Pressure Systems. They are heavy-duty enough for food-grade liquid as well. Just like you, we also thought that these were unnecessarily overkill for aquaristic purposes, but it has been proven that these are the ONLY qualified Check Valves for protecting your expensive CO2 equipment (Regulator & Cylinders) from saltwater with a pressurized Kalkreaktor pushing it backward vigorously. Takes 4/6 mm (ID/OD) or 1/8" airline tubing.

so far, free flowing Product Review by KURT SEIDLER (Posted on 5/25/08)

Excellent!

Comments: I bought a brass check valve to replace one that had locked up, and so far it is allowing gas to flow well. I still want to know why my original valve shut up, as this new one appears to be identical.

great buy!!! Product Review by iamonreeftank (Posted on 8/30/07)

Excellent!

Comments: a "must have" for calcium reactors, only one very small problem w/ this product - it doesn't come w/ any instructions at all. couldn't really make out the directional arrow at first, had to do trial and error to be sure. otherwise, excellent product.

Great!

Comments: When I was attempting to dial in my cal reactor and couldnt get the bubble count right I decided to replace my old valve with this. Once I did everything worked great. Marine Depot had the lowest price I could find and I had it at my door in no time at all.

Works for a while then fails Product Review by JEFF DROBICK (Posted on 1/24/12)

Comments: I have owned a calcium reactor for several years now. I have had 2 or 3 of these brass check valves fail over time. It will work for a while then it starts locking up and not allowing CO2 flow. This makes dialing in the bubble/minute count a huge issue. I know it is the check valve and not the regulator as when I took it off I have been fine. Try an alternate.
