The Gardena L-piece 25 mm x 1/2"-external thread is used within the Gardena sprinkler system to connect the pop-up sprinkler S 80 as well as the turbine pop-up sprinklers T 100 and T 200 to the end of the pipe. 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 L-piece is self-sealing.
