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. The spout features a limited swivel of 140 deg to help prevent accidental water flow outside sink. You can install with confidence, knowing that DELTA® faucets are backed by our lifetime limited warranty. Industry standard is based on ASME A112.18.1 of 500,000 cycles.
