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
My suggestion is that something is probably wrong w your pipe/hose. Mine did the same thing until I realized it was b/c of the cheap irrigation tubing the builder used. I used the 1/2 tubing from HD and the seal was perfect. You will have to cut the pipe and then bend it so that you can pull it out w/o destroying the coupling. I would just cut it out throw it away and start fresh. I had to replace the hose for the entire front yard this year bc of the same problem

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
That is a rather difficult task. Save yourself some time and just use a pair of pipe cutters and cut it out, then use needle-nose pliers to bend the tube and pull it out from the compression coupling. If you try doing it while attached you will destroy more 1/2 tubing than you would if you just cut it out. Once pulled out the coupling should be good to go, as long as you didn't destroy it getting the tube out of it..

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 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

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 Excellent Time Saver This is one of those small inventions that saves a lot of time and trouble when connecting 2 1/2 drip pipe ends together. Just push in from each side and your done, no clamps or plastic bumps when placed back on bed. I must have 6-7 of these in my irrigation parts box in my garage.
