Non-return valve for shower and kitchen – White, odor-proof, unmarked, one-way drain valve

Selected Material: The shower stopper is made of high-quality silica gel and PP plastic. Its smooth, burr-free surface not only prevents injury to your hands during use, but also features an acid- and alkali-resistant valve core that fits tightly around the corrosion-resistant seal, keeping odors, wastewater, and rodents out. Easy to Install: The odor-proof sealing stopper is 6.5 cm high and 5.5 cm wide, and can be installed in drain holes with a diameter of 3.7 to 5.2 cm. Ready to use without removing floor tiles or pipes, making it easy to install. Double Layer Design: The odor trap adopts a double hollow design that can drain a wide 360° area, with a drainage capacity of 36 liters/minute, providing fast and unobstructed drainage. The inverted wedge-type internal coupling surface secures the inner core, preventing it from falling out or moving. Function: Drain pipe seals are mainly used to be inserted into pipes, floor drains, and under-sink drains to prevent odors, dirty water, and pests from entering, backing up, and overflowing, keeping the space clean, tidy, and uncluttered. Multiple Uses: The odor-proof shower stopper is widely used for drain openings in bathrooms, kitchens, toilets, washing machines, sinks, bathtubs, showers, and other locations.
