Silicone Anti-Odor Sewer Seal Ring Drain Connector

Reliable Anti-Odor Seal for Drains and Appliances

Keep bathroom, kitchen and laundry areas fresher by blocking sewer odors and backflow at the source. This silicone sewer seal ring and floor drain connector creates a tight, water-resistant barrier in your drain pipe, helping stop smells, splashes and insects from entering your living space.

Made from flexible, elastic silicone, this drain plug is designed to fit securely inside common household sewer and drain pipe sizes. The variable-diameter body is suitable for inner pipe diameters of approximately 35-40 mm, 45-50 mm, 60-65 mm and 70-75 mm (check your pipe size before purchase).

The automatic rebound design opens to 90° while draining and closes again when not in use, helping to maintain a consistent barrier against odors and pests. Installation is plug-and-play: simply insert the appropriate size into the pipe connection for washing machines, kitchen sinks, vegetable sinks, wash basins or bathroom floor drains-no special tools or advanced plumbing skills required.
