Data Sheet

• 360° Swivel Gooseneck
  Integrated swivel union allows full rotation of the gooseneck without loosening components, maintaining seal integrity and enabling 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 minimize stagnation to support purity.
