Self-Closing Drain Core – Keep Your Sink & Floor Drain Fresh and Clean

Upgrade your bathroom or kitchen drain with this smart Self-Closing Odor-Proof Drain Core. Engineered with a gravity-flush self-closing valve, it creates a reliable seal when not in use — keeping unpleasant sewer odors and small insects from entering your home through the drain opening. Made in Mainland China.

Key Features

  • Self-Closing Valve: The gravity-actuated valve closes automatically after water drains, forming an effective barrier against sewer gases and crawling insects.
  • Odor-Proof Design: The sealed structure minimizes unwanted odors from rising through sink or floor drains, keeping your space smelling fresh.
  • Insect-Proof Barrier: Prevents small insects and pests from entering through the drain line — ideal for kitchens, bathrooms, and laundry areas.
  • Hair Catcher Function: The built-in strainer catches hair and debris before they enter the drain, making routine cleaning quick and hassle-free.
  • Removable Inner Strainer: Simply lift out the inner strainer for easy cleaning and daily maintenance — no tools required.
  • Durable Materials: Constructed from a combination of ABS, food-grade silicone, and electroplated stainless steel for lasting corrosion resistance and a polished finish.
  • 3-Inch Round Fit: Sized at approximately 7 × 8 cm (2.75 × 3.15 in) to fit standard 3-inch round sink and floor drain openings.

Frequently Asked Questions

Q: What drain sizes is this self-closing drain core compatible with?

A: This drain core is designed to fit standard 3-inch (approximately 7 × 8 cm) round sink and floor drain openings, commonly found in bathrooms, kitchens, and laundry rooms. Please measure your existing drain opening before purchasing to confirm compatibility.

Q: How does the self-closing odor-proof drain valve work?

A: The drain core uses a gravity-flush self-closing silicone valve. When water flows through, the valve opens to allow drainage. Once water stops, the valve closes automatically under its own weight, sealing the drain opening and preventing sewer odors and insects from coming back up through the pipe.

Q: Is the inner strainer easy to remove for cleaning?

A: Yes! The inner strainer is fully removable without any tools. Simply lift it out, rinse away accumulated hair and debris under running water, and place it back in the drain core. Regular cleaning helps maintain optimal water flow and hygiene.

Q: What materials is this drain core made from?

A: The drain core is made from a combination of ABS plastic, food-grade silicone, and electroplated stainless steel, offering durability, corrosion resistance, and a sleek, polished appearance that suits most bathroom and kitchen aesthetics.
