High Quality Material The combination of chrome-plated brass and high-quality ABS hard plastic creates a rust-proof sink drain plug for your 40 mm drain pipe. It is odorless, corrosion-resistant, wear-resistant, not easily deformed, and built for long-term use. Effortless Operation The sink drain cover can be adjusted to the depth of the pipe by hand and secured firmly with a nut. Hair and dirt pass through easily, preventing clogs and allowing waste to flow directly into the drain. Rubber Ring Design The drain plug features a rubber seal that ensures a secure closure, allowing your sink to hold water without leakage. The extended side rails on the wings of the sink stopper provide a stable fit, preventing movement or shaking. Easy Installation This flush stopper has a simple design and is easy to install. After confirming the size, remove the old plug and replace it with this new one. Suitable for all standard sinks.
