Product Features: Product Technologies: DIAMOND™ Seal Technology: Delta® DIAMOND Seal Technology utilizes a ceramic disc valve with a real diamond coating to produce a faucet that will last up to five million uses. That's twice as long as the industry standard, guaranteeing a lifetime of leak-free, trouble-free performance. Delta Innoflex PEX supply lines are included with DIAMOND Seal faucets, so everything you need is in one box. Touch-Clean® Spray Holes: The Delta® soft, rubber Touch-Clean Spray Holes make it easy to wipe away unsightly calcium and lime buildup with the touch of a finger, helping prevent your product from developing a mineral blockage which could reduce water flow. While other kitchen faucets, shower heads and hand showers may require chemical cleaners and soaking time to dissolve mineral buildup, Delta products featuring Touch-Clean Spray Holes can be simply wiped clean for improved performance and an instantly refreshed look.
