Welcome to our shop Introducing our 360 Adjustable Drippers - these automatic irrigation drippers are designed with 8 spray holes to ensure precise and efficient watering. With the ability to adjust the water flow, these drippers can automatically clean and start the erosion flow channel, preventing clogging issues. These drippers are suitable for various tubes, as they have a 1/4 inch thread connection that fits 4mm/7mm diameter tubes. By using these adjustable micro drippers, you can save up to 70% water compared to traditional watering methods. This precision watering system delivers the right amount of water slowly and precisely to the root zone of your plants. These drippers have a wide range of applications and are perfect for agriculture, lawns, gardens, patios, greenhouses, and watering potted plants. For best results, we recommend putting the pipe in plastic drip irrigation drippers in water at 75~80 degrees Celsius for 10 seconds before assembling. This will ensure an airtight seal once the tube has cooled down. Note: 1. Please allow small size error due to manual measurement. Thanks for your understanding. 2.
