The Gardena T-piece 25 mm x 1/2" external thread is used within the Gardena sprinkler system to connect the S 80 pop-up sprinkler as well as the T 100 and T 200 turbine pop-up sprinklers in the pipe layout. Thanks to the patented "Quick & Easy" connection technology, the pipe installation or removal is tool-free and can be done simply by rotating the connection by 140°. For waterproof and secure operation, the threaded connection of the T-piece is self-sealing.
