The Excursion Series First Stage Regulator delivers reliable performance for demanding subsea operations. Built with a balanced diaphragm design, this first stage maintains consistent delivery across varying depths and tank pressures. The environmentally sealed construction protects internal components from saltwater corrosion, while marine-grade brass with matte black chrome finish ensures durability in harsh underwater conditions. DIN connection provides a secure, leak-free interface. Four low-pressure ports (two per side) and two high-pressure ports (one per side) offer flexible hose routing for custom configurations. The compact design minimizes drag and streamlines your rig for efficient underwater work.
