Setting up a drip irrigation system? This HOINCO 300-piece fittings kit has everything you need to connect your 1/4 inch tubing. You get 100 straight barbs, 80 tee connectors, 40 elbow fittings, 40 end plugs, and 40 four-way couplings - seriously, that's enough to handle most garden layouts. The barbed design means no tools, glue, or clamps required - just push the tubing firmly over the barbs for a tight, leak-resistant connection. Made from high-strength plastic that won't corrode or deform easily, these fittings are built to last through seasons of use. They work with standard 1/4 inch drip irrigation tubing (4mm ID, 7mm OD) and are perfect for gardens, flower beds, patios, greenhouses, or agricultural watering systems. The installation is so simple - if the tubing is stiff, just use a hair dryer to warm it up slightly before inserting the fittings. This kit helps you create efficient watering systems that save water while keeping your plants happy and healthy. Much better than hand-watering, and way more customizable than sprinklers!
