Zeagle F8 Yoke Regulator with F8 Octopus

The Zeagle F8 Regulator with F8 Octopus is a US-made scuba regulator designed for reliable performance across a range of diving conditions. Its low-profile first stage reduces tank valve extension and optimizes hose routing for a clean, streamlined setup in any diving gear configuration. With more than 20 improvements over prior models, the F8 aims for smooth breathing and dependable operation in demanding environments.

For divers seeking versatility, the F8 combines a completely new platform second stage with an environmentally sealed first stage and a pneumatically balanced design. The first stage uses marine-grade black chromed brass and features a balanced diagram design, a dry environmental seal with hydro transmitter, a precision stainless steel HP valve with an advanced polymer seat, and high-performance porting. It ships factory-ready for EAN/Nitrox to 40% O2, making it suitable for scuba and diving gear setups that require mixed-gas capabilities and reliable performance across conditions.
