21.0 mm 97% 98% alumina ceramic seal disc for faucet

_01.jpg

  Alumina ceramic seal discs for faucets are essential components that contribute to the leak-free operation

of faucet systems. These discs, typically made from high-grade alumina ceramic material, serve as sealing elements

within the faucet mechanism. 

 

Sealing Function: The ceramic seal disc is designed to create a watertight seal within the faucet assembly, preventing

water from leaking when the faucet is closed or not in use. The precise machining and smooth surface of the ceramic

disc ensure a tight seal to maintain water integrity.

Compression Sealing: When the faucet handle is turned to close the water flow, the ceramic seal disc is pressed against

another surface, such as a metal seat. The pressure applied during closure compresses the ceramic disc against the seat,

creating a secure seal to stop water flow.

Resistance to Wear: Alumina ceramic seal discs are highly wear-resistant, protecting against abrasion and maintaining their

sealing effectiveness over time. This durability ensures long-term performance and minimizes the need for frequent maintenance

or replacement.

Temperature Stability: Alumina ceramic's high-temperature stability allows the seal disc to maintain its properties even when

exposed to hot water in the faucet system. This thermal stability contributes to the reliability of the seal under varying temperature

conditions.

Chemical Resistance: Alumina ceramic discs are resistant to chemicals commonly found in water systems, ensuring that the seal

remains unaffected by water additives or contaminants. This chemical resistance enhances the longevity and effectiveness of the

ceramic seal disc.
