Includes a drain strainer, drain fitting, flexible drain pipe and siphon trap that work together to prevent leaks, keep water flowing and block sewer odors. Key benefits — why you need it Leak‑resistant connection: thickened sealing ring at the connection point prevents water from escaping where the parts meet. Easy installation and maintenance: parts are designed for straightforward assembly and convenient access for routine cleaning. Long‑lasting and rust‑resistant: components are made from rust‑resistant (rostfrei) material for durable performance and low maintenance. Flexible and tear‑resistant pipe: the flexible drain pipe resists tearing and allows easier routing under sinks with tight or awkward spaces. Odor isolation: the integrated siphon function traps water and blocks unpleasant drain smells.
