Item # LG-DDSU500K-R2 — Swivel Laboratory Faucet, Deck Mount, Duraline Control Valve, 500KΩ·cm Purity Light, Handle on Right, Natural Polypro

• Material & Applications
  Natural Polypro material rated for high-purity and general laboratory water service (Type II & III).
  Suitable for distilled, deionized, ultra-filtered, and general laboratory-grade water systems.
• Swivel Feature
  Integrated swivel union allows full 360° rotation of the gooseneck while maintaining seal integrity, providing flexibility at the point of use.
• Control Valve
  Zero-dead-leg Duraline control valve with smooth 120° rotation from full flow to closed.
  Positive stop at off position prevents over-tightening.
  Renewable design with replaceable cartridge (meets SEFA 7-2010-8.2a).
• Purity Light
  Integrated 500KΩ·cm resistivity sensor with dual-color LED indicators.
