As part of the GARDENA Sprinklersystem � the GARDENA T-piece 1" x 3/4" female thread serves the installation of the Drain Valve (Art. No. 2760) within the run of the pipe. Through the patented "Quick & Easy" Simple Connection Technology, pipe assembly or -disassembly is done without tools through simple turning of the screwed fitting by 140�. For water-tight, safe operation, the thread connection of the T-piece is self-sealing.
