Zeagle F8 Diving Regulator

Zeagle F8 Diving Regulator – The best regulator from Zeagle

Zeagle introduces a new regulator model featuring a completely redesigned second stage platform. The F8 name is derived from the well-established Zeagle Flathead series regulators. This all-new design is Zeagle’s top regulator, with more than 20 new improvements. Zeagle regulators are manufactured in the USA under strict quality control at their own facility, using state-of-the-art equipment and procedures. Your regulator is one of your most important pieces of equipment—no matter what type of diving you do, you can do it better with Zeagle. The F8 has a very low profile, barely extending above the tank valve, and positions low-pressure hoses directly to the sides, a configuration preferred by many divers.

The first stage regulator is made from marine-grade black chrome-plated brass and features a balanced diaphragm design that is environmentally sealed. The diaphragm transmits pressure changes to the internal mechanism, eliminating the need for surrounding water to enter it. The benefit of this design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine, or pool acids, which can cause corrosion and mineral buildup, degrading regulator performance.
