F8 1st Stage Yoke

ZEAGLE – F8

The legendary Zeagle first stage, complemented with a new high-performing flagship 2nd stage. The result, the best performing diaphragm regulator on the market today.

In partnership with Atomic Aquatics, we engineered 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 we’ve ever made. 

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.

New Neoflon seat:

Our conical precision high-pressure valve provides much greater reliability and service life compared to conventional designs, while improving responsiveness and performance at all breathing rates

Work of breathing at heavy* demand:

0.72 Joule/Liter

*198 (60M) depth, 750 psi inlet, 62.5 RMV (liters per minute respiratory volume)

Like all Zeagle regulators, The Flathead-7 comes factory ready for use with EAN/ NITROX to 40% O2.
