Hydrofarm Active Aqua Elbow Connector (10 Pack), 3/4"

These claim to fit 1/2 inch pipe, but they are way too small. My bad - other reviewers reported this.Thank you Amazon for a great return policy.

Yes these are perfect. Other reviews said they don't fit 1/2" poly pipe. I don't know what there all thinking and or dreaming about but these do fit 1/2" poly pipe. A perfect fit. U have to work with it a bit, but a perfect nice tight fit. Great perfect product !! Perfect for any 1/2" pipe and perfect for any auto 1/2" rubber hoses. I give perfect 5 stars. Highly recommended.

These took quite a bit of effort to install on the half inch tubing. At first I wasn't able to get them to go into the tubing. Then I found that if you heated the tubing up with a match or some other flame source the tubing was flexible enough to allow one to get these elbows installed.

I use these on the five-gallon buckets that I am using to grow produce using the Kraky Method of Hydroponics. I attach a flexible tube to them so I can see the water level and know when to add nutrients.

I read mixed reviews about these elbow connectors before my purchase, but decided to take a chance and I'm glad I did. I used them to eliminate potential kinks in 1/2" PVC tubing used with a submersible pump and a fountain in my outdoor pond. These were a perfect match with the tubing I'd purchased and provide a snug, water tight fit and they were exactly what I needed to make my installation as clean as possible. I suspect that they'll hold up fine for my needs for several seasons.

Using these for a custom build water fountain project. They’re well made and should do the job.

Worked perfectly for my 1/2" car engine vacuum line seems to be good quality plastic

Under pressure these popped off, get Spears elbows much stronger more and deeper barbs

Purchased this to use with standard 1/2" drip irrigation tubing (.700 OD), these are much to small, and will not work.Standard poly drip tubing (like you would buy at home depot - orbit brand, etc.) is about 15mm ID, and these elbows are only about 13mm OD.Otherwise, I'm sure these would be fine for other applications. Not a high quality part (slightly mis-shaped and the barbs aren't sharp), but would probably work fine for tubing around 13mm ID.

worked well with the 1/2" active aqua fittings and tubing is not identical size to 1/2" fittings from our local hardware store as there is a slight difference in size.

Total garbage I was sceptical of the crappy reviews but when I got the product it’s just total crap it leaks then pressed into there own hose because the manufacturing quality is so bad after it leaked I tried to remove it and it broke garbage product not worth your time go to a local hardware store

Not 0.5 inch other than hat will work if getting all 3 T L I other wise don’t buy unless only need 1/3 but for hydro DIY buy all 3 and some comalnt tubing if posiblemother sideman nothing fits or works lol :$ trust me ! A bit smaller than 0.5inch but bigger than hydro flow 0.5 inch by a lot!

Not tight inside the 1/2" poly tube but works (not much but leaks, with pressure regulator; so I used metal clips too)
