What is a ceramic disc cartridge?

The cartridges are the most critical component in a faucet. Kingston Brass utilizes state-of-the-art ceramic cartridges for a lifetime of drip-free dependable usage.
The cartridge is a self-contained system consisting of two ceramic discs with quarter-circle openings rotating one on top of the other and controls water flow by (a) lining up or (b) covering the openings. Due to its nature, ceramic carbide does not wear out due to friction, however special care should be taken in flushing all the lines prior to installing your faucet since any debris in the line may crack one or both of the ceramic discs.
