F8 1st Stage Yoke with F8 2nd Stage

In partnership with Atomic Aquatics, the F8 offers over 20 different improvements on everything from inner mechanisms and materials to exterior controls and aesthetics. The F8 breathes better, works harder and lasts longer than any other regulator made by Zeagle. The F8 1st stage has a sealed spring chamber to prevent 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 hose directly out to the sides.
