Introduce

Toilet flange gasket is a rubber gasket used to seal the connection between the toilet and the drainage system. It seals and prevents leaks by being installed between the flange at the bottom of the toilet and the ground or drain pipe. When the toilet is fitted, the flange gasket rests on the toilet’s flange, which links the toilet to the drain pipe. When the bolts and nuts used to secure the toilet are tightened, the flange gasket compresses, establishing a seal and preventing sewage leaks.

Certification standard

  • NSF/ANSI Standard 61: The National Sanitation Foundation (NSF) and the American National Standards Institute (ANSI) created this standard to evaluate the health impacts of materials involved with drinking water systems. Toilet flange gaskets may need to meet this requirement to avoid contaminating drinking water.
  • ASTM D2000 is a standard developed by the American Society for Testing and Materials (ASTM) to specify the physical, chemical, and other qualities of rubber goods. This standard may apply to toilet flange gaskets, which are commonly constructed of rubber.
  • EN 681: The European Committee for Standardization (CEN) produced this standard to evaluate the performance and quality of rubber and plastic seals. Toilet flange gaskets may need to meet this standard in order to be approved for the European market.
  • WRAS Certification: The UK Water Regulations Advisory Scheme issues this certification to examine the compliance of materials and goods related with drinking water systems. To be allowed for use on the UK market, toilet flange gaskets may need to meet WRAS certification criteria.
Advantage and function
  1. The primary function of a toilet flange gasket is to produce an efficient seal to prevent leaking in the space between the toilet and the drainage system. It seals connections and prevents sewage from leaking onto floors or walls, so preserving cleanliness and reducing water damage.
  2. Anti-odor: A toilet flange gasket may help prevent sewage from spilling through the connection, reducing the stink. It keeps smells from entering the bathroom through the drain pipe, making it more pleasant and cleaner to use.
  3. Reduces vibration and noise: Gaskets can also be used to lessen vibration and noise generated by water draining. It functions as a buffer, absorbing and lowering stress and vibration during drainage, resulting in less noise and pain.
  4. Durability: A high-quality toilet flange gasket has a long service life and is comprised of wear-resistant, chemical-resistant, and aging-resistant rubber material. They can survive repeated use and environmental changes while still providing dependable sealing performance.
  5. Simple installation and replacement: Gasket installation and replacement are straightforward. Typically, simply place the gasket over the flange at the base of the toilet and fasten it. If the gasket has to be replaced, just remove the old one, clean the flange, and replace it.
Conclusion

Toilet flange gaskets are rubber seals used to prevent leaks between the toilet and drainage system. They are designed to be installed between the toilet’s flange and the ground or drain pipe, ensuring a secure connection. These gaskets are certified by various standards, including NSF/ANSI Standard 61, ASTM D2000, EN 681, and WRAS Certification. They are designed to prevent sewage leaks, maintain cleanliness, and reduce water damage. They also serve as anti-odor, reduce vibration and noise, and are durable due to their wear-resistant, chemical-resistant, and aging-resistant rubber materials. Installation and replacement are simple, with the gasket typically installed over the toilet’s base and fastened. They can also be easily replaced by simply removing the old gasket, cleaning the flange, and replacing it.
