As part of the GARDENA Sprinklersystem – the GARDENA T-piece 25 mm x 3/4" male thread serves to connect the Turbo-driven Pop-up Sprinkler T 380 (Art. No. 8205-29), and the Pop-up Oscillating Sprinkler OS 140 (Art. No. 8220) 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.
