This quick connector set is every connector you’ll ever need. The set includes a garden hose nozzle, hose splitter with a shut off valve, and 20 rubber washers. The two way splitter is one of the really cool pieces because it allows you to use two hoses at once. They can be used for outdoor soaker, sprinkler, and drip irrigation. All of the pieces are well made and durable. The connector pieces are made of PVC plastic that are lead free and Eco-friendly. I like that the pieces are orange so that if dropped that can be easily found and the dogs can’t find them first. =) All of the pieces have attached to hoses and other accessories just fine. We’ve also not had any problems with leaking either.
