Silicone Drain Plug – Anti-Odor Floor Drain Seal for Sink & Bath

Silicone Floor Drain Plug – Anti-Odor Sewer Sealing Trap for Kitchen & Bathroom

Keep your kitchen and bathroom smelling fresh with this 7-layer anti-odor silicone drain plug. Designed for easy plug-and-play installation, this floor drain device creates an airtight seal between your drain pipe and sewer line — blocking unpleasant odors, insects, bacteria, and moisture from creeping back up through your pipes.

Key Features

• 7-Layer Anti-Odor & Anti-Overflow Design: The drain pipe and sealing ring fit flush together with zero gaps, keeping sewer gases and overflow firmly blocked.

• Variable Diameter Compatibility: Fits drain pipe outer diameters of 18–35 mm and sewer pipe inner diameters of 35–40 mm and 45–50 mm, making it suitable for most standard plumbing setups.
• Durable Eco-Friendly Silicone: Soft, elastic, aging-resistant silicone construction is waterproof, leak-proof, and built to last through years of daily use.
• Pest & Odor Barrier: Effectively blocks cockroaches, insects, bacteria, and viruses from entering through floor and sink drain openings.
• Wide Application: Compatible with washing machines, vegetable sinks, wash basins, bathtubs, and most household drain pipes.

Why Upgrade Your Drain Seal?

Standard floor drains without a proper sealing plug can allow sewer gases, pests, and bacteria to enter your living space. Upgrading to a quality silicone drain plug is one of the simplest and most affordable ways to improve home hygiene.

Frequently Asked Questions

Q: What pipe sizes is this silicone drain plug compatible with?

A: This floor drain plug is designed for drain pipes with an outer diameter of 18–35 mm and sewer pipe inner diameters of 35–40 mm or 45–50 mm. It fits most standard residential sinks, bathtubs, washing machine drains, and wash basins.

Q: How does the automatic rebound mechanism work?

A: The plug uses a 90° open/close design. When water flows through, gravity opens the silicone flap automatically. As soon as water stops flowing, the silicone material springs back to its closed position, creating an airtight seal that blocks odors and pests without any manual action required.

Q: Is this drain plug safe for food-contact areas like kitchen sinks?

A: Yes. The sealing ring is made from environmentally friendly silicone — a material that is non-toxic, waterproof, and aging-resistant — making it safe for use around kitchen sinks, vegetable wash basins, and other food-preparation areas.

Q: Does this plug prevent insects from coming up through the drain?

A: Absolutely. The tight-fitting silicone seal closes completely when not draining, acting as a physical barrier against cockroaches, small insects, and other pests that may try to enter through the sewer pipe.
