Hello! Thank you for asking about the Brizo 64375LF-PCLHP kitchen sink faucet. DIAMOND Seal Technology is an integrated ceramic valve cartridge featuring one ceramic disc and one diamond-embedded ceramic disc. As the two discs move against each other, the diamond-embedded disc polishes the uncoated disc, removing calcium and mineral deposits. Eliminating wear on seals and creating an impenetrable barrier with no metal parts exposed to water. We hope this information helps. To order this faucet, click add to cart and fill in your details.
