JADUFHU Drain Seal Plug, 7-Layer Waterproof Reusable Stopper, Magnetic Self-Sealing Anti-Odour Silicone Fits 45-50mm Pipe for Washing Machine, Dishwasher, Kitchen & Bathroom (1PCS)

【Premium Silicone Material】This drain seal plug is crafted from high-density food-grade silicone material, featuring excellent toughness, anti-deformation, anti-aging and corrosion resistance. Different from ordinary inferior plastic plugs, it will not crack, harden or deform after long-term use. It withstands high and low temperatures and resists daily detergent and limescale erosion, ensuring durable and reusable performance for household drainage use. 【Magnetic Self-Sealing Design】Equipped with upgraded bottom magnetic induction structure, the drain stopper realizes automatic opening and closing. It opens smoothly for fast water drainage when water flows, and seals tightly after drainage stops. This intelligent rebound design avoids manual operation and helps relieve drain backflow and residual sewage problems. 【7-Layer Anti-Odour & Anti-Backflow】Adopting 7-layer reinforced silicone sealing ring structure, this pipe plug builds a multi-dimensional airtight barrier for drainage pipes. It helps reduce sewer odor, harmful gas reflux and small insect entry, relieving common odor issues in bathrooms and kitchens. The multi-layer sealing structure also improves pressure resistance and lowers the risk of sewage leakage. 【Universal Pipe Compatibility】This drain seal plug is universally designed to fit 45mm to 50mm inner diameter drainage pipes, matching most standard household pipeline specifications. It is widely compatible with washing machine drainpipes, dishwasher water outlets, kitchen sink drains, bathroom floor drains and vanity drain pipes, covering most household drainage scenarios. 【Tool-Free Installation】The integrated plug-and-play structure enables simple installation without tools or professional plumbing skills. Just insert the plug firmly into the drain pipe to complete tight sealing. It is also easy to disassemble and clean for daily maintenance, helping keep drainage pipes clean and hygienic with less effort.
