[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), helping to avoid common issues such as inconsistent sizing and poor fit. Suitable for most household sinks. Made of stainless steel and brass with rust and corrosion resistance: The drain fitting is constructed from stainless steel and brass, formed in one piece to effectively resist rust and corrosion from household wastewater and oil. 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 spring switch to complete installation. No tools required—installation and removal take only 3 seconds, offering convenience and ease of use. Pop-up valve design: The sink plug helps prevent sewer odors by sealing the drain pipe. The pop-up mechanism remains stable when pressed and does not tip over, ensuring reliable sealing and easy emptying. Dual black silicone seals enhance stability and leak resistance. Built-in filter basket: Unlike conventional drains, this sink plug features an anti-clogging filter basket designed to catch debris and prevent small items such as jewelry, rings, and dirt from entering the drain pipe, reducing the risk of clogs.
