[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 to 36 mm (1.34 to 1.4 in), helping to avoid common issues such as inconsistent sizing and poor fit. Suitable for most household sinks. Made from stainless steel and brass, this one-piece constructed drain resists rust and corrosion caused by household wastewater and oil. Includes a thickened silicone seal. Installs in seconds—simply remove the old plug, insert the new sink plug, and press the spring switch to complete installation. No tools required. Assembly and removal take only seconds, offering added convenience. Features a pop-up valve that helps prevent sewer odors by sealing the drain pipe. The plug remains stable when pressed and does not tip over, ensuring reliable sealing and easy emptying. Two black silicone seals enhance stability and improve leak resistance. Built-in basket strainer filter helps prevent clogs by trapping debris and keeps small items such as jewelry or rings from falling into the pipe. Material: Stainless steel. Color: Gold. Package includes: 1 x sink plug. Light and display differences may cause slight color variations between the image and the actual item. Measurement tolerance: ±1–3 cm.
