The LG-DDSU-R1 PVC Laboratory Faucet is engineered for distilled, deionized, RO, ultra-filtered water, and chemical dispensing applications. This deck-mounted model features a 360° swivel gooseneck for flexible positioning and a Duraline zero dead leg control valve for precise, reliable flow control in high-purity environments.
360° Swivel Gooseneck Integrated swivel union design allows full rotation of the gooseneck without loosening components, maintaining seal integrity for easy positioning.
High Flow Performance Delivers up to 2.4 GPM at 80 PSI for efficient dispensing in lab environments.
Removable Serrated Barb Tip Accepts 1/4"–1/2" I.D. tubing; removing the tip leaves a 1/4" Female NPT outlet for accessories.
Duraline Control Valve PTFE-sealed with an encapsulated modified PTFE shut-off seal for low gas permeability, improved creep/extrusion resistance, and extended service life.
Zero Dead Leg Design Crevice-free internal geometry helps prevent stagnation to support purity.
Handle Orientation – Right Handle Right-hand handle configuration for user preference and layout flexibility.
SEFA-Guided Handle Marking Black handle with white marker and “DI” text per SEFA No. 7 recommended practice for DI water applications.
Renewable Cartridge Uses replaceable Duraline cartridge (DL-RC180-PVD) for straightforward serviceability.
Standard Inlet Connection 3/8" Female NPT inlet; includes Jaco 3/8" O.D. compression tube x 3/8" MNPT fitting.
Deck Panel Mounting Includes 3" through-deck nipple shank, ring nut, and gasket; fits 1" diameter hole, max deck thickness 3".
Pressure Rating 180 PSI @ 72°F (PVC).
