Customer Questions & Answers

I installed 6 of these couplers, 3 are not sealed properly and water is spraying from one end. How can I fix the problem?

Asked by: AA
Considering some of them leak and some don't, I would agree with one of the other comments that the leaking ones probable aren't inserted far enough. There are two small posts about half way through the coupling; the tubing should bottom out against those. Try pushing the pipe farther into the coupling where they are leaking and that should fix the problem. Don't try removing the pipe—you will likely damaging the connection and it will then leak anyway.

How do I remove them from the drip tube again?

I used them to connect 2 pieces of tube, then had to shorten one end. I cut the coupling loose and tried to remove it from the tube, but could not do so. Is there a way to remove the poly tube from the coupling so it can be used again? Thanks!
Asked by: WB
Should pull off with little force depending on what you fitted them to. They fit very snug with companies tubing as they should, dip in hot water before pulling off fitting should loosen up its grip if not... Then resort to cutting as I wouldnt suggest any degreaser or chemical products compromising the tubings water supply.

Why is this product described as 1/2 inch, but no measurement of this product resembles? Outer Diameter said to be .700 = 70% of an inch but clearly measures a full 1 inch? I understand previous reviews stating it had worked for them, but misinformation such as these diameters going unoticed is a very poor review circuit as a consumer of this product I've been mislead by false information which is most crucial when in the market to build a propperly working irrigation system...

1/2 in. 0.700 O.D. Compression Coupling is rated 4.5 out of 5 by 15.

Building a garden irrigation system, I stopped at HD to grab these fittings. BIG MISTAKE!!! Sure you can get them to work with tubing that is integratable (Buying the companies tubing) but this is described as 1/2 and .700 O.D. Meaning Outter diamtere is 70% of an inch, and I.D. with mic is 3/4 so where is 1/2 inch coming from?? Stick 1/2 sharkbite or everbilt in these couplings and tell me I'm wrong?? Cheap machined Chinese plastic is what I bought from a company who can't even measure they're products or care to provide accurate specifications. Returning and buying another irrigation brand with hopes I.D. and O.D. are accurate and a more common diamters. As HDepots stocked irrigation products are a joke, should I try Lowes? Or buy from a small online supplier who will provide a better service. Not long til Home Depot is history like HQ!!

Rated 5 out of 5 by from Works really well, but you need to know a couple of things I've been using these on my garden drip irrigation system for about ten years. They never leak, they never get disconnected, and they seem (so far) to last forever. BUT, you should keep the following in mind: 1. Assembly is much much easier on a warm sunny day. The more uncomfortable you are, the easier these are to assemble. It can be somewhat difficult in chilly weather (though the 1/2-inch fittings are easier than the 1/4-inch varieties). 2. "Never get disconnected" means even when you want them to. Think carefully before you push the tubing into the connector. It is almost impossible to remove it - - so much so you are usually better to cut it off and thrown it away.

Rated 4 out of 5 by from Meant for thick walled half inch, not the thin stuff. These are a good price for what they are. But you should note that there are different thicknesses of tubing and these must be meant for the thick walled stuff as they don't hold on to the thin walled stuff. They blow off the thin walled 1/2 inch if you put normal water pressure on them. The ones with the green inside ring on the end is for the thin walled stuff. These have black inside walls. Not a bad thing, you just have to be aware of what your pairing them with...

Rated 5 out of 5 by from Easy to use Simple connector holds onto tubing well and doesn't seem to leek. Just make sure that you cut your tubing to the appropriate length before inserting into the connector because it is a pain to remove, and you may damage the connector in the process.

Rated 5 out of 5 by from easy to use i wasn't sure exactly what i was going to get it is described as a compression fitting but it is more like a quick connect. you simply shove the end of the hose in and it locks the hose in securely it does take a good deal of force but not awful. I have several of these in use for about a month now with no leaks or complaints.

Rated 5 out of 5 by from works really well. works very well for repairing the sprinkler tubing. just cut at a decent length to eliminate the area of crack. i use two pieces, one on each side of the crack. i usually have a bad piece cut out at a length of 8-10 inches, enough to easily press on the fittings on each end. i also spread a little vaseline in the fitting to make the tube slide in easier. using two of the fittings requires a new joiner piece between the fittings but it gives you more flexibility when assembling the tubing
