Ceramic-on-ceramic valves traditionally use grease to maintain a frictionless surface for smooth handle motion. Over time, the calcium builds on the ceramic and the grease wears away, requiring extra effort to move the handle. Our patented diamond-on-ceramic design is not only greaseless, but actually polishes the ceramic with each use, keeping the operation like-new for life.
Our integrated PEX waterways have been stress-tested at 500 psi and 200°F. Using an electron beam versus chemicals to crosslink the waterways not only eliminates any odor or taste, but the lines will not crack when frozen nor kink, corrode or fail in any manner. And they are much easier to install, manipulate and cut than standard copper risers.
Our goal was to ensure that water never comes into contact with any metal once inside the faucet. But the key components of our faucet body, handle, stainless steel stem and bonnet nut remain constructed with the same uncompromising strength and feel of metal that you’ve come to expect from a quality Delta faucet that’s nothing short of brilliantly engineered.
Built to last 10 times longer than the industry standard, Delta’s new faucet models featuring Diamond™Seal Technology provide an exclusive new water delivery system that uniquely harnesses the durability of the hardest substance in existence along with our one-piece PEX waterway construction. To assure the highest quality, we stress-tested this new technology at 500 psi and 200°F.
