What Is Diamond Seal Technology?
Diamond Seal Technology takes full advantage of the hardest natural substances known (diamonds). 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. All Diamond valve cartridges feature a handle limit stop which makes it easy to limit the range of the handle motion for hot water from a full flow to a 50/50 mix. This feature helps protect you and your children against potential scalding.
Diagram Diamond series faucet features:
  • Lead-Free: Once water is inside a Diamond series faucet, it does not come in contact with metal.

  • Long Lasting: The new Diamond Seal Technology is built to last 10 times longer than the ASME 112.18.1 (500,000 cycles) standard.

  • Diamond-on-Ceramic Valves: Are designed to be greaseless and actually polish the ceramic with each use, keeping the valve like new for many years.

  • Less Hassle: New and flexible InnoFlex PEX-C waterways makes installing these faucets simple and painless.

  • Leak Resistant: One-piece supply lines, Diamond plated ceramic valves, and no dynamic seals means these faucets are built to last and resist leaks.


Frequently Asked Questions

Q. "Do faucets have lead?"
A.Faucets made with brass will have a certain amount of lead (roughly 3% to 8%) contained in the brass as part of the manufacturing process. The Diamond Seal faucets completely separate water contact from any metal in your faucet by using Pex-c waterways.

Q. "How does lead content in brass faucets affect me?"
A.Water is a solvent, probably the best known solvent on earth. As such, water will absorb metals, minerals, and chemicals that it comes in contact with over a period of time. A faucet that has brass waterways can be susceptible to this process. Water sitting in your faucet can leach the lead out of the brass and enter your water system.

Q. "What is a Brilliance® finish?"
A. A Brilliance® finish is designed to not corrode, tarnish, or discolor. It is developed by embedding molecules deep into the surface, creating a bond that is nearly indestructible. This process is known as Physical Vapor Deposition (PVD).

Q. "Do you offer replacement faucet cartridges for these faucets?"
A.Yes. The replacement cartridge is #RP50587 and can be purchased here.

Q. "Are real diamonds used?"
A. Yes, but not the diamonds you would typically find in a jewelry store. Carbon (the source of diamonds) is taken and electrically charged. Then, using high amounts of pressure, fused to a ceramic plate, creating a diamond coating that is clear and nearly indestructible.

Q. "What is an InnoFlex waterway/supply line?"
A. Innoflex is a crosslink polyethylene (PEX-C) that is commonly used in the U.S. These new faucet waterways have a unique composition that makes it stronger than copper and easier to work with because it's flexible.
