Questions & Answers

Will this work well if I take it off and on many times?

I need a variety of tubing configurations in my garden boxes. I would like to swap them out as I plant different crops. Can I use this as a universal base? I’m wondering if it would start leaking after several cycles.
Asked by: oldVermonter
The universal nut lock fittings are designed to be re-used. The nut can be unscrewed and the tubing can be easily removed from the fitting. Replacing the tubing and re-using the fitting should not cause any leakage to occur after tightening the nut.

Mine are leaking

Using two of these to replace a section of irrigation tubing. I don't understand why I'm getting a leak from both. No PTFE required, no tools, just cut a replacement section of pipe to length and put it on...
Asked by: Steve
They may be leaking because: a) you did not get the nuts tight enough, be sure you are wearing gloves (leather work gloves would be better than cotton gloves). (I have used an adjustable wrench at times to get them just a little tighter, but I have also split one of the nuts when I tried to get it too tight.); b) the tubing is installed too short and the end of the tubing is not butted up against the flat lip part of the insert (always give the tubing a little extra length, you can trim it back if it is a bit too long); c) the tubing is too long and the connector is being torqued at an angle internally allowing the leak; d) there are dirt particles inside your tubing where the tubing slips over the insert; e) there are dirt particles on the insert; f) there are dirt particles inside the connector where the insert fits inside the connector. Be sure these areas are as clean as possible. I know, tough to do when working in dirt. Also, an occasional drip is okay, I have had the Chinese finger puzzle types leak too.

The currently available coupling for 1/2" drip system lines I find are really a problem. I don't know if the lines buried in my yard are 0.65" or 0.700" or 0.710" or what. I bought a 10 pack of "Store SKU #1001194633", on the bag it says "Fits all brands of 1/2" or 5/8" tubing (0.63"-0.710" O.D.)" I now see that the HD web site limits it to "Accepts any manufacturer’s O.D. tubing from 0.630" to 0.700". " I found that even with the tubing out of the ground many times I couldn't force the tubing into the coupler. Much less when bent over into a hole under a bush. I've gone through about a dozen of these 1/2 in. Universal Nut-Lock Coupling "Store SO SKU #531677", they work beautifully every time. They are really Universal. Too bad it seems that most stores no longer carry them and I had to order them from the web. Which when you have a split waterline the week or so to get them is really a problem. But now I always keep at least a couple on hand.

This product is 101% better alternative to other options for repairing breaks in landscaping water products. It is a very quick, easy and efficient method of correcting leaks for us....especially those of us who have reached our 70s but continue to rely upon and enjoy our own abilities to resolve issues around our home. There is only one problem.....YOU DO NOT STOCK THEM IN OUR STORES. My neighbor attempted to purchase through your online as I did and was notified the product not available online either! Apparently I purchased the last 16 units available....! This is not good service after we alerted all of our nearby neighbors of the ease of using this product....we all suffer frequent leaks in this area ...Chandler, AZ, due to the intense heat. We would appreciate an alert if and when these units are again available.

Rated 5 out of 5 by from The perfect coupler! These are the only couplers that work well. They are not picky on the sizes of drip line and then never fail and very easy to install. Easy to reuse too, I won't use any other type. I wish they made an end cap with this design.

(0.700 O.D.) Poly Drip Tubing. I've been using this connector for more than 10 years and have so many buried in the yard. They are a little more expensive than the Dig compression connectors but are much easier to work with (at least for me) because as long as I cut the existing damaged hose at a 90 degree angle I can hand tighten the connections then use either a pair of channel locks or crescent wrenches or one of each to tighten up the connections, which also means I can dig up a smaller section of the yard to make the repairs.
