JADUFHU

【Magnetic Automatic Sealing】Featuring an optimized built-in magnetic self-rebound structure, these drain stoppers deliver sensitive and stable automatic opening and closing performance. The valve opens freely under water pressure for unobstructed fast drainage, and closes tightly via magnetic force once water flow stops. This passive sealing design requires no manual operation and helps reduce sewer gas backflow, odor diffusion and small pest entry throughout the year. 【Industrial-Grade Silicone】Made of thickened high-elastic silicone material, these dual drain plugs boast superior anti-deformation, anti-corrosion and anti-aging properties. They resist daily wear and tear, frequent water flushing, detergent corrosion and temperature changes, maintaining soft elasticity and stable sealing performance for years. Tougher than ordinary plugs, they are not easy to break and support long-term repeated use. 【7-Layer Tight Sealing】Designed with 7-layer stacked reinforced sealing rings, the plugs form a fully enclosed waterproof and odor-proof barrier inside 45-50mm standard pipes. The multi-layer structure fits closely with the pipe wall, helping relieve sewage backflow, odor overflow and water leakage, and improving common household drainage problems such as peculiar smells, dampness and pest infestation. 【Wide Application】These universal drain plugs fit all standard 45-50mm inner diameter drainage pipelines, matching mainstream European household pipe specifications. They serve as ideal replacement accessories for washing machine drainpipes, dishwasher water outlet pipes, kitchen sink drains, bathroom floor drains and vanity drainage systems, covering most common household drainage scenarios. 【Easy Installation & Maintenance】No tools, no glue, no professional installation required. The plug-and-play design allows quick installation in seconds by directly inserting the stopper into the drain pipe. The smooth silicone surface is easy to clean with simple water rinsing. The 2-piece set supports spare use or multi-position installation to meet diverse household drainage demands.
