All-Brass Floor Drain Core – Anti-Odor & Insect-Proof Insert

All-Brass Floor Drain Core – Anti-Odor, Insect-Proof & Self-Sealing

Upgrade your bathroom, kitchen, or toilet floor drain with this premium all-brass floor drain core insert. Engineered with a self-closing ABS gasket mechanism, this drain stopper automatically opens when water flows and seals shut the moment drainage stops — blocking sewer gases, unpleasant odors, insects, and backflow from ever entering your living space.

Whether you're replacing a worn-out drain core or upgrading for better hygiene, this plug-and-play insert fits most standard floor drain pipes and installs in seconds — no tools required.

Key Features

• Premium Brass Construction: Durable all-copper body built to resist corrosion and withstand daily use in wet environments.
• Self-Sealing Design: ABS gasket opens automatically under water pressure during drainage, then closes by gravity when water flow stops — creating a complete airtight seal.
• Anti-Odor Barrier: Keeps sewer gases and foul smells sealed below the drain, maintaining a fresh-smelling bathroom or kitchen.
• Insect & Pest Prevention: Fully sealed closure prevents insects, cockroaches, and small pests from crawling up through drain pipes.
• Fast, Unobstructed Drainage: The strainer-style body allows rapid water flow while catching debris — no slow drains or pooling water.
• Wide Compatibility: Suitable for bathroom floors, shower areas, kitchen floors, toilet rooms, and sewer pipe openings.
• Easy Plug-and-Play Installation: Simply insert into your existing floor drain — no special tools or plumbing knowledge needed.

How It Works

1. Draining: When water enters the floor drain, its weight pushes open the bottom ABS gasket, allowing water to flow freely and quickly down the pipe.
2. Sealed State: Once water flow stops, the gasket closes automatically due to gravity, forming a complete seal that blocks gas, odors, insects, and backflow from rising through the drain.
