F8 FIRST STAGE

The F8 1st stage has a dry-sealed spring chamber (to stop freezing at water temperatures below 40 degrees F). All delicate parts of the 1st stage including the main spring are sealed behind the Clear hydrostatic diaphragm away from the effects of salt or other contaminants in the water, making it environmentally sealed. It is very low in profile, barely extending above the tank valve, and places the low pressure hoses directly out to the sides, in a pattern preferRed by many divers.

  • Balanced diaphragm design and the environmentally sealed ambient chamber ensure top performance in any condition.
  • Redesigned environmental seal cap and yoke knob enhance ergonomics & design aesthetics.
  • Percision machined neoflon seat harder more reliable material, keeping you diving longer.
