Delta MagnaTite uses a powerful integrated magnet to pull your faucet spray wand precisely into place and hold it there so it stays docked when not in use. Delta faucets with DIAMOND Seal Technology perform like new for life with a patented design that reduces leak points, is less hassle to install, and lasts twice as long as the industry standard. Bar/prep faucets with Touch-Clean holes allow you to easily wipe away calcium and lime build-up with the touch of a finger. You can install with confidence, knowing that faucets are backed by our lifetime limited warranty. The industry standard is based on ASME A112.18.1 of 500,000 cycles.
