I was trying to set up four nano shrimp tanks and run mini sponge filters off one air pump. I tinkered and tinkered with t splitters and plastic valves but could not get the flow right to all four. Then in the wee morning hours I remembered seeing this aquarium coop four way metal gang valve at my LFS and thought “aha…this may be the answer”. Luckily I had today off work. I bought the gang valve and more tubing and an extra check valve (I didn’t have those set up in an ideal manner). Well it took much less time tinkering and works perfectly! I want a gentle flow to my tiny tanks and am able to get that now.

These are the best they divide up the air perfectly no air leaks well-made better than you could find at other stores

Installing this on my air system noticeably decreased it's efficiency. I eventually discovered one of the valves was defective, or somehow damaged in transit. When I emailed customer support they shipped out a free replacement within hours. Nice! The replacement is working flawlessly and I'm satisfied. I have no reason to think this is at all a common issue, but it happened to me.

I'm very happy with my purchase! They're high quality and durable. I glued magnets on them to attach to my rack and it has made it so accessible and easy to modify tanks.

Good product. All metal holds up well. Best part is customer service it's like buying things from a friend. Supper service. Great shipping. Thx coop

On the good side it makes for a clean install.

On the not do good side, there is not a lot of fine control. For nano tanks probably not the best choice.

For a few more dollars I could piece something together with T-splitters and individual Ziss valves.

Was very disappointed that the valve did not work with the coop sponge filters and their nano pump. I have a small and a medium sponge filter connecting to the valve and I turned off the extra 2 slots that was not being used and the nano pump did not have enough power to push air through .. not even for 1 filter.. I swapped the nano air pump with a tetra 10g and both filters turned on no problem and are easily adjustable.. I wish it would’ve worked with the coop nano air pump tho .. but other than that I like it

Works perfectly, currently running 3 sponge filters in my guppy breeding tank. fittings are the perfect size to pair with the aquarium co op air lines 😬

I have a few of these now and they work great. I bought 1 of these a few months ago and so far so good. I just bought a few more for another setup and they work as well as the first.

Perfect for my settup way easier u can adjust everything.

Bought this to try out and replace a plastic marina one that I hated. Love the design and was surprised to discover it's chromed brass with ball valves. Very high quality for a very low price! I attached it to the side of tank with suction cups that have hooks on them. Will definitely buy again!

I use it as air splitter to multiple tanks. Each one can be adjusted to whatever flow you need in each individual tank. I love to order from Aquarium Co-Op. They ship out immediately and their products work exactly as needed. Never had any problems whatsoever. Thank you for always taking good care of your customers.

I purchased this to run air to a large outdoor quarantine tank I set up for a sick pond fish. It worked really well, the valves moved smoothly and stayed where i set them. I used all four valves to run sponge filters and airstones. My air pump produces a fair amount of air and the manifold handled it quietly and without any problems. The compact size would likely be a plus for anyone with an indoor tank where space is often a consideration.

Good gang valve. Air lines fit snugly.

These gang valves are the backbone of my vertical tank spacing air delivery to the filters. By putting air in both sides I achieve really strong flow in all four nozzles. The valve levers don’t get stuck and they don’t break meaning that I can readily regulate flow. I have never had the metal ones from the co op fail in any way

Great quality!

This valve is well built and simple to use. Good for very fine adjustments

Has fine adjustment capabilities, fits in airline holders. But the valves are stiff enough where you have to brace with other hand.

By far better control it’s tight, no finicky plastic parts I wish they had more parts made this way for the air system in my tank

I cannot believe how much I love these things. I have well over a dozen tanks, and virtually everyone of them has one, or shares one of these with another tank. They are so versatile.

Even if I only using 2 of the valves I have them on some tanks. It is so great to be able to add a breeder box, pop a line on to inflate a bag of fry I am going to sell. Like I said, it adds versatility.

I recently needed to cycle 4 sponge filters. I took off the plastic cap, and used a poorly made made air pump I never really liked. It has 2 outlets that share the same internal pump. So if there is pressure on one side it affects the other. I took the plastic cap off the side of the gang valve, hooked a tube onto both outlets of the air pump and into both side of the valve. For the first time ever, this unusable air pump is being used.

I also have a small linear air pump. It has a spaghetti of lines coming off the manifold. At the end of each line I have one of these going into my rack system. It is amazing how well I can fine tune each sponge filter or airstone with the individual valves.

On the farthest tank, I am using one of the valves as a pressure release because I am under utilizing the pump.

I could go on and on, but... bold statement... It is my favorite and most used Co-op product. (so far)

Great valves

Made one line two for aesthetics. High quality materials and easy to dial in.

Works as intended! Feels sturdy and provides solid control

It splits and controls the flow. If any valve is more than about half way open it makes a loud high pitch sound. Not a huge deal since I want gentle flow, but not expected, especially since I'm using a tiny air pump.

High quality and amazing service 🔥🔥🔥

This saved me from so many different little connections and cuts in my air line. I have never had an easier time setting up my sponge filters and it keeps all the airline looking nice and tidy. A must have in my opinion.

Very simple packaging easy to use and the best part you can daisy chain them which helps me. Hoping to order the air pump for the next upgrade to my system
