From the Manufacturer The design was inspired by a strong presence in nature like that of tree with reaching branches. The majestic appearance of the Linden tree inspired the Linden kitchen faucet - a fresh design that will bring life to any kitchen. This elegant yet approachable faucet brings a delightful personality to the kitchen. Delta's exclusive DIAMOND Seal Technology uses a valve with a tough diamond coating to bring you a faucet built to last up to five million uses. Plus, it keeps water inside the faucet out of contact with potential metal contaminants. Who knew a faucet could be just as beautiful on the inside?
