10 Pcs Barbed Tee 1/2 inch Tubing (1/2" ID x0.6-0.63" OD) 16mm to 1/4 inch Irrigation Tube Anti-Drop Quality Fitting (Fits 13mm ID / 4mm ID)

I've purchases both the hose adapter set (with one 1/2" to four 1/4 adapter, a standard American garden faucet/ hose socket to 1/2" hose connector, and end cap) and the first time i ordered, it came as ordered. The second set (summer 2023) had a different threading on the faucet adapter. But, they sent a replacement set right away (got it a couple days after posting my replacement/ return order), and the replacement is correct. Also purchased the set that has a butch of different connector like corners, end caps, strait l straight connectors, and 1/²" to 1/4" adapters. Those have all been perfect. Good stuff. Just not sure the usefulness of the severalstraight through connectors... I'll typically just use longer lengths of tubing if need be. Would have preferred elbows instead, but I suppose they're useful if you've got several shorter lengths of hose. But the other bits are exactly what I needed. If ordering the set with the hose/ faucet adapter, just be ready to request a replacement if they send the wrong part, cause apparently someone isn't very proficient at packaging quality control...See pics for the differences in threading between the correct one (larger, fewer threads), and the incorrect (smaller, but more threads) connectors, and they fit, or not, depending on the adapter. Again, good stuff, if they send the correct part.

I got these when some cheaper fittings kept leaking (non-screw variety). I set up a DIY hydroponic garden so leaks are a death sentance for my plants. These haven't had any leaks through half a season and look to be going strong. They're easy to attach to soft vinyl hoses (not the rigid irrigation hose) and there's a good variety so that I only needed one pack for all my needs. Would definitely recommend.

I am not sure what kind of 1/2" hose I am using. The caps are an extremely tight fit over the outside diameter of the hose, and I have to fold the hose to fit it through the cap. As a result, I am very sure these will not leak. The barb fits tightly in the inside diameter of the hose, and the assembly tightens up nicely when the nuts are installed. A big bag of couplings at a decent price means I can patch together shorter pieces of hose as needed.

very easy to attach to the drip irrigation supply tubing.

I used this adapter to create a removable connection to my sprinkler valve. If you warm the hose end a bit it’s a lot easier to push onto the adapter. Screw down end piece makes it very secure!

Works like it’s suppose to

These are in fact metric and will not work with 1/2” tubing. However i have a 5/8 reamer that resolves the issue. If i had a bunch of connections to run i’d return or trash them. Since I only have a few connections to make I’ll just ream out the cap and move on. My bad not the sellers.

They work great, don't leak, and go on pretty easy but extremely tightly. I have them running now at multiple locations and they are working perfectly. For my hydroponics system I have a 1/4 hose splitting to two more 1/4 hoses, and have had no problems. Highly recommend!

Could have included more than one valve in the package, but all in all easy to install and compression fittings work great.

Great product and arrived on time thank you so much

Easy to setup and no leaks.

Perfect

THe green part doesn't fit over my 1/2 tubing.
