When using these connectors to attach 3/16 inch (4.6mm) branch tube into the side wall of ½ inch (13mm) supply tube, use an installation tool (available separately - product code - LDK, see you may also like below) to create a neat hole in the supply tube.

Use the screw threaded end of the connector to securely fit the connector into the hole created.

Design includes stainless steel clips enabling quick & easy connection or disconnection of branch tube, so if your watering needs increase within the garden or greenhouse extending or modifying the system is simple.
