Zeagle F8 Regulator

The first stage of the Zeagle F8, paired with an iconic second stage, is one of the highest-performing diaphragm regulators on the market today.

In developing the F8 regulator, we partnered with Atomic Aquatics and designed more than 20 improvements, from internal mechanisms and materials to external controls and aesthetics.

What is the result? The F8 breathes better, performs better, and lasts longer than any other regulator we have ever made. Our precision tapered high-pressure valve delivers greater reliability and service life compared to conventional designs, while also improving responsiveness and performance across all breathing rates.

• The first stage features a dry-sealed spring chamber to prevent freezing in water temperatures below 4.4°C (40°F).
• The first stage is coated with a flat black chrome finish to protect the brass from corrosion. A highly durable black PVD coating is used on high-use port plugs to protect them from wear and corrosion.
• Anti-surge front cap design with a new stylized “Z” logo.
• Smaller mouthpiece with ultra-soft silicone and tear-resistant, color-accented “Bite” tabs.
• Improved dry exhaust valve with reduced breathing effort on exhalation.
• Inhalation effort adjustment knob for improved grip and style.
• Threaded cover for added security.
• Heat sink with improved materials and increased surface area to dissipate cold.
• Zirconium-plated inlet tube for enhanced corrosion resistance.
• Improved response and tear resistance in the inhalation diaphragm.
• Redesigned front cover and inhalation adjustment knob use co-molded components for easier grip.
• Co-molded silicone mouthpiece for better fit and reduced jaw fatigue.
• Redesigned shuttle valve with improved tolerances.
• Patented seat-saving orifice.
• Low-pressure second-stage seat.
• Second-stage superalloy spring.
• Made in the USA – Berry Amendment compliant.
