The Zeagle F8 first stage, complemented with a flagship 2nd stage, is one of the best performing diaphragm regulators on the market today.

When building the F8 Regulator, we partnered with Atomic Aquatics and engineered over 20 improvements on everything from inner mechanisms and materials to exterior controls and aesthetics.

What?s the result? The F8 breathes better, works harder and lasts longer than any other regulator we?ve ever made. Our conical precision high-pressure valve provides greater reliability and service life compared to conventional designs, while improving responsiveness and performance at all breathing rates.

• First stage has a dry-sealed spring chamber to stop freezing at water temps below 40 degrees F
• First stage is coated with flat black chrome plating in order to protect the brass from corroding. A very durable black PVD is used to coat the high use port plugs, to protect from wear and tear and corrosion
