The Application of Gaskets in Bathroom Facilities

In the field of bathroom facilities, gaskets, though small in size, play a crucial and essential role in the sealing, waterproofing, leak prevention of equipment, and the protection of water quality. The main materials of gaskets include NBR (Nitrile Butadiene Rubber), silicone rubber, EPDM (Ethylene Propylene Diene Monomer), and peroxide-cured EPDM, each with distinct characteristics:

NBR (Nitrile Butadiene Rubber): It has excellent oil resistance, making it suitable for bathroom environments where there may be contact with oil stains.

Silicone Rubber: It features outstanding high and low temperature resistance and good chemical stability, enabling it to adapt to different water qualities and temperature changes.

EPDM (Ethylene Propylene Diene Monomer): It has strong weather resistance, being able to resist the erosion of ultraviolet rays, ozone, and chemical substances, and also has good water resistance.

Peroxide-cured EPDM: It has passed a series of stringent international certifications, such as the AS NZS4020 certification in Australia/New Zealand (ensuring safety when in contact with drinking water), the JFSL 370/JIS S3200-7 certification in Japan (compliant with hygiene and safety standards), the KIWA certification in the Netherlands (recognition of quality and sustainability), the ACS certification in France (safety for contact with drinking water), the KTW/W270/W534/DVGW/UBA-LL and other certifications in Germany (multidimensional safety and hygiene testing), the USA NSF61 certification (in line with the safety standards of drinking water equipment in the United States), the Ö-NORM/LMG certification in Austria (local quality and safety specifications), the UK:WRAS/WRC certification (compliant with drinking water contact in the UK market), the European EN681-1 certification (unified quality and safety standards), and the PAK/PAH certification (free from harmful polycyclic aromatic hydrocarbons), comprehensively ensuring quality, safety, and environmental protection. Other materials have passed ordinary certifications to ensure basic performance.

I. Rubber Sealing Gaskets: Guarding the Sealing Line of Bathroom Equipment Rubber sealing gaskets are widely used in various key parts of bathroom equipment:

Water Meter: The rubber sealing gaskets at the water inlet and outlet (mostly made of EPDM or NBR materials) prevent water leakage, ensuring the accurate measurement of the water meter. This avoids water loss and measurement deviation caused by leakage, and guarantees the long-term stable operation of the water meter.

Faucet

At the connection between the faucet and the water pipe, the rubber sealing gasket fills the gap to prevent water from leaking at the interface, ensuring the sealing of the water supply system.

The sealing gasket between the valve cartridge and the valve seat (the material can be selected as NBR, silicone rubber, or EPDM according to the environment) ensures the sealing when the water flow is turned on and off, reduces water leakage, and extends the service life of the faucet.

Toilet

At the connection between the water tank and the toilet body, it prevents the water tank from leaking.

At the connection between the sewage pipe and the sewer, it forms a good seal, eliminating sewage leakage and the upward return of peculiar smells.

Shower Head

At the connection between the spray head and the rod, it ensures a tight connection and prevents water from seeping out.

At the connections between both ends of the hose and the faucet and the spray head, it prevents water from leaking at the hose connection. Meanwhile, it cooperates with the aerator to optimize the water flow, making the water output softer.

Hose Connector: It ensures a tight connection, prevents water leakage, and can adapt to pulling from different angles, ensuring flexibility and durability in daily use.

Soap Dispenser: The seal prevents the soap liquid from leaking, ensuring the smooth output of the soap liquid and maintaining the normal use of the soap dispenser.

Bathroom Spray Gun: The seal ensures that there is no leakage during high-pressure water spraying, guaranteeing a stable spraying effect and meeting the cleaning and other requirements.

II. Rubber Sealing Gaskets for Filters: Optimizing Bathroom Water Quality and Equipment Protection

Characteristics

Strong Filtration: It covers specifications such as 60 mesh with a wire diameter of 0.18, 60 mesh with a wire diameter of 0.15, and 40 mesh with a wire diameter of 0.19, effectively intercepting impurities such as sediment, rust, scale particles, and insects.

Good Corrosion Resistance: Having passed the drinking water standards certifications of multiple countries, it can adapt to different water qualities and is not easily corroded when in contact with water for a long time.

Good Adaptability: With various specifications and sizes, it is convenient for installation and can be adapted to various bathroom equipment.

Functions and Scenarios in Bathroom Facilities

Household Bathroom: Installed at the faucets, shower heads, toilet water inlets, and bathtub drain filters, it improves the cleanliness of the water used, protects the equipment, and extends its service life.

Kitchen Water Use: Used at the kitchen sink faucets, front-end filters of water purifiers, and dishwasher water inlets, it ensures the purity of kitchen water and protects electrical appliances.

Other Scenarios: Although not in household bathrooms, in the bathroom systems of commercial places such as hotels and restaurants, as well as in the industrial pretreatment stages with high water quality requirements (such as food and beverage processing, pharmaceuticals, etc.), it can also maintain the operation of water-using equipment and water quality standards.

In conclusion, different types of gaskets, by virtue of the advantages of their respective materials, play an indispensable role in the bathroom field, from sealing, waterproofing, and leak prevention to water quality optimization and equipment protection, creating a safer, more comfortable, and more durable bathroom experience for users.
