Delta® MagnaTite® Docking 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 which reduces leak points is less hassle to install and lasts twice as long as the industry standard. Kitchen faucets with Touch-Clean® Spray Holes allow you to easily wipe away calcium and lime build-up with the touch of a finger. Industry standard is based on ASME A112.18.1 of 500 000 cycles.
