The GARDENA T-Joint for Spray Nozzles as part of the GARDENA Micro-Drip-System serves to fix spray nozzles in the 4.6mm (3/16") Supply Pipe; this is done in combination with a Pipe Guide (Art. No. 8327-20) or Pipe Clips (Art. No. 8379-20). The T-Joint is especially suited for extending the spray nozzles in combination with the Extension Pipe (Art. No. 1377-20). The patented "Quick & Easy" connection technology ensures especially easy installation to a 4.6 mm (3/16") Supply Pipe. Five T-Joints and five caps are included.
