Delta Faucet Co.’s patent-pending DIAMOND Seal Technology is an exclusive new water delivery system that eliminates contact with potential metal contaminants such as brass, copper or lead, keeping water as pure as it entered the faucet. It also provides guaranteed protection from leaks and drips. Comprised of a next generation DIAMOND valve and InnoFlex waterways, the system reduces the number of potential leak points, simplifies installation and provides long-lasting performance.
The DIAMOND valve is an integrated ceramic valve cartridge featuring one ceramic disc and one diamond-embedded ceramic disc. As the two discs in the DIAMOND valve move against each other, the diamond-embedded ceramic disc constantly polishes the uncoated ceramic disc, removing calcium and mineral deposits and ensuring smooth, consistent operation over the life of the faucet.
