For me this is the best coupling to repair or install 1/2 in. (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.

          I have acres of trees and shrubs watered by drip lines. I have problems with damage by squirrels eating my 1/2 in lines or my gardeners weed wacking. These are a fast/easy repair.

            Works Well but Beware!
            I used this product as a coupling between my drip pipes when I built a planter box. I had drip pipe inside my planter box, and I used this to connect that to the feeder pipe coming from the irrigation system. It made it easy to disconnect the planter box from the drip pipe line whenever I wanted to move the planter box for cleaning the deck. Beware though - do not overtighten the outer nuts with wrenches more than a half-turn. If you use crescent wrenches or vise grips to tighten the nuts, then you will break the coupling. It is not that rugged. After breaking 2 of these, I learned to hand tighten as much as possible, and then only one half turn with a wrench was needed to make it water tight.

              These things are great, way better than the standard push in couplers. The store should stock them instead of having to order them.

              I've used these for years and they endure the harsh desert summers. I've reused them as another section of drip line fails - they are very well made!!!
