All About Delta Faucet Diamond Seal Technology


Most kitchen and bathroom faucets are replaced for one of two reasons. Either they look outdated, or the faucet has broken. In terms of the latter, a broken faucet can mean anything from a faucet that leaks to a faucet with a handle that is impossible to move.

Such lack of mobility is typically caused by lubrication in the cartridge of the faucet handle wearing off. Delta’s Diamond Seal Technology improves on this complication by removing the lubrication all together, and creating faucets that will last for decades.

Diamond Seal is simple yet complex technology. Traditionally, two small plastic circular discs will move back and forth inside the cartridge of the faucet handle as the handle is moved. These discs have lubrication between them to prevent the cartridges from grinding and locking together. Eventually, the lubrication can evaporate and wear off, making the faucet handle difficult to turn. Delta Diamond Seal uses carbon discs embedded with diamond, making each valve cartridge sleek yet durable. The surface of each cartridge is so smooth, no lubrication is needed. This ensures there will be no wear on the cartridge for the life of the faucet, keeping the hardware in mint condition from the first day onward.
