ATL5445W Ball Valve for Regulating Water Flow, 1/2-Inch

Got one to reduce the filter pump output on a Fluval Spec for a Betta. Seems to work good. But woah, this sucker was big. I knew it would be for a 1/2" tube, but I didn't expect the valve to be that big. Nothing wrong with that, tho.Valve is nice and tight. This might be a problem to adjust in tight areas, but if it isn't in a tight area, it's good to make sure the valve stays at the position you place it.It's kind of funny, this one is under the "Two Little Fishes" brand, but it looks exactly the same as a generic version of this valve, under regular hardware and not aquarium use. The graphic and logo on it are the same. So if you can find this valve under a different brand cheaper, go for it. This one probably isn't even made by Two Little Fishes, just packaged by them.There's someone else selling this same valve on Amazon for twice the price, plus shipping. So this one is the better deal, if you have Prime or are buying at least $35 worth of merchandise.

This product is great. I own about ten. I have never used clamps and have never leaked. They grip .5 inchinch inner dismater rubber hose so well that once it is on you have to cut them off. Problems I want to have.However, first time buying, I thought I was buying "Two" for the price of one because of the company name. Laugh. Its sad to be me every day. :). But to be clear you are getting "one" valve from a company called "Two little fishes" not "two" from a comapny called "little fishes". I am wrighting this because as dumb as I am, I hope and pray there is at least one person who is dumber.

I use this on a Finnex Mini Canister Filter inflow pipe, and this thing works really well. I can adjust it to the smallest flow level, or completely off. An absolute must for maintenance or feeding baby brine shrimp etc. All LFS should carry this product.

Really great product and easy assembly with clear instructions. There are a few things that you will need though in order to make it run1) Some sort of powerhead air pump depending on the size of your tank2) a flow valve regulator to adjust the intake of water for getting the flow rate just right3) 1/2 inch plastic tubing. Which I got from Lowe's for like .19 cents a foot. You may have to heat the tubing up with hot water in order to make it go on certain parts4) your desired filter media. I did rox carbon and it cleared up my cloudy water that nightI hope this helps in case you are confused on what else you need to buy.

I use them to cut off the visibility spout of my Waverunner. The fishies do this job perfectly. Unfortunately they break, if you try to turn the knob in the wrong direction. I gave 5 stars nevertheless because of the low price. If you use the product very carefully, the valve works well and easy. Personally, I would prefer a better quality for a higher price, but it is still the best product for my purpose that I could find. I do not want to use anything that corrodes in the ocean water.

I bought this ball valve to use inline in some tubing going from my canister filter to a chiller on my 20 long axolotl tank. It works great. It allows me to cut off the chiller when I want to...for whatever reasons I may want to...and it doesn't leak or let any water through. It fits the tubing perfectly and seems well made.If you need a cutoff valve for your line, this is a great choice.

The valve seems to be of good quality, but, contrary to normal conventions where tubing sizes are specified on the basis of outside diameter, this valve is intended to fit on tubing with 1/2" inside diameter. Normally, this valve would be specified as a 5/8" valve. I was able to force my 1/2" standard wall thickness tygon tubing onto the valve, but it was a challenge.

These are great little all valves. I use them to control the flow of my phosban reactor. I got this additional one to make disconnection leak free when cleaning my reactor. Just turn the input and output valves off and disconnect the hoses while the reactor is in a bucket. Been using for over 18 months and no issues whatsoever. Love these ball valves!

VERY GOOD PRODUCT.

Great quality at a cheaper price.

Arrived in gooid time and works fine.
