Our range of 4mm EZY Flex tube is ideal for connecting 4mm micro irrigation. The flexible PVC material provides a strong, reliable grip onto any sharp 4mm barbed fitting. With the secure grip you get from the EZY Flex tube, you can “reliably” run your micro irrigation to your pots, planter boxes, hanging baskets and throughout your garden beds. Gone is the hassle & worry, of the system blowing apart! The connection between the tube & the fitting, is most important. This connection has two main functions. Firstly the tube must stay attached to the 4mm fitting under water pressure & secondly, the tube must provide a water tight seal. EZY Flex provides BOTH! Due to the flexible characteristics & strength of EZY Flex, it can reliably grip onto any 4mm barbed inlet and therefore stay attach to the product. With this tight conforming fit over the barb, EZY Flex provides a watertight seal, everytime!
