A Lifetime of Reliable Performance

Experience a faucet that performs like new for life with Delta DIAMOND® Seal Technology. Our patented design reduces leak points and lasts twice as long as the industry standard*—ensuring leak-free operation for the life of the faucet. Everything you need is together in one convenient box, including integrated supply lines. Using diamonds, the hardest naturally-occurring substance on Earth, we’ve engineered a faucet that’s longer lasting, leak-free and less hassle to install. Who knew a faucet could be just as beautiful on the inside?

 *Industry standard is based on ASME A112.18.1 of 500,000 cycles.
