The Gardena T-piece 25 mm x 3/4" external thread is used within the Gardena sprinkler system to connect the turbine pop-up sprinkler T 380 and the pop-up square sprinkler R 140 in the pipe layout. Thanks to the patented "Quick & Easy" connection technology, the pipe installation or removal can be done tool-free by simply turning the connection 140°. For waterproof and secure operation, the threaded connection of the T-piece is self-sealing.
