[New Design, Wide Application] This drain fitting is optimized and improved based on standard drains. It fits drainage holes with an inner diameter of 34 mm - 36 mm (1.34 - 1.4 in), ensuring a secure fit and avoiding common issues such as size inconsistency. Suitable for household use. Made of stainless steel with rust and corrosion resistance: The drain fitting is constructed from stainless steel and formed in one piece to effectively resist rust and corrosion caused by domestic wastewater and oil stains. Includes a thickened silicone seal for enhanced sealing. Quick installation in 3 seconds: Simply remove the existing drain plug by hand, insert the new sink plug, and press the switch to complete the installation. No tools required—installation and removal can be done in seconds, offering convenience and ease of use. Pop-up valve design: The sink plug prevents sewer odors by sealing the drain pipe and avoids backflow. The valve remains stable when pressed and does not tip over, ensuring reliable sealing and easy drainage. Dual black silicone seals enhance stability and leak resistance. Integrated filter basket: Unlike conventional drains, this sink features a built-in anti-clogging filter basket designed to catch debris. It helps prevent small items such as jewelry, rings, and dirt from entering the drain pipe, reducing the risk of clogs.
