Diamonds are the hardest substance known to man, and Diamond Seal Technology takes full advantage of this property. Delta's exclusive Diamond Seal Technology uses a valve with a tough diamond coating to bring you a faucet built to last up to 5 million uses – plus it keeps water inside the faucet out of contact with potential metal contaminants.
With its durable components and simple construction, a Diamond Seal Technology faucet lasts 10 times longer than the industry standard (ASME 112.18.1, 500,000 cycles). One-piece InnoFlex waterways with PEX-C tubing make Diamond Seal Technology faucets simple to install.
The handle limit stop on Delta’s Diamond Valve cartridge makes it easy to limit the range of the handle motion for hot water from full flow to a 50/50 mix. This feature is the smart choice to protect sensitive skin from scalding.
