Review: GREAT LITTLE ADAPTOR ITEMS - I'm the tool / supplies junkie in my house, and as a female, I'm all about DETAILS DETAILS DETAILS. These are great quality, and I would purchase them again. I've had no issues with them. The connection is tight, the threads a great consistency. Seal them with teflon tape, is my suggestion. I don't like fighting metal on metal to pull it apart, using the old fashioned GOO GLUE GUNK...I call it, nor do I want leaks linking metal to plastic, which is common in the irrigation system. Teflon tape...there are different kinds for different intended uses...pay attention when buying...works great. I HATE LEAKS, and I'm the one ALWAYS designated to handle the plumbing. Rarely do I call a plumber, so that should tell you how successful the teflon tape is for me.
Review: Good buy!!! - Perfect fit. Worked amazing
