The 6mm Barbed Tee is a fitting that is perfect for all irrigation and hydroponic uses. It is designed to join poly pipe together and has a unique barbed design that ensures a secure and lasting connection of your pipes, while allowing an uninterrupted flow of water or air. The flow dynamics of Barbed Tees enables an uninterrupted flow. It is ideally suited for weaving through garden beds and into pots. The installation process is simple: first punch a hole into either a 13mm or 19mm poly pipe mainline for a 6mm take-off adaptor. This allows you to then tap into the water source. Push the 6mm take-off fitting into the Minicape drip tube, then into the punched hole. Run the Minicape tube to its maximum length. For shaped gardens or shorter lengths, use 6mm fittings to form a loop connecting back into the mainline, or layout tube and shape using tee’s & elbows. The barbed end seals inside drip tube and it is suitable for around trees & garden beds. It is ideal for low pressure watering applications. The 6mm Barbed Tee comes in various sizes: 4mm, 6mm, 13mm, 19mm, 25mm, and 32mm.
