This set includes 20 barbed elbow connectors made for 1/2 in. drip irrigation tubing. These fittings work with most standard 1/2 in. drip tubing that has an inner diameter between 0.560 and 0.600 in., offering wide compatibility for most irrigation setups. Crafted from sturdy plastic, they resist deformation and breakage to provide a long-lasting service life. Installation is straightforward, with no need for glue, tools or clamps their barbed ends grip the tubing tightly to form a secure, leak-proof connection, and heating the hose end can further ease the fitting process. These elbows are perfect for gardens, greenhouses, flower beds, patios and a variety of agricultural watering systems, helping users adjust or expand their irrigation networks with minimal effort. Color: Browns/Tans.
