Designed for scuba diving gear reliability, the Atomic Aquatics B2 Regulator, Yoke Sealed with Color Kit and Z2 Octopus pairs a chrome-plated brass first stage with the signature second-stage design from Atomic's T3. This setup delivers smooth breathing and consistent performance for diving in underwater environments. The package is Nitrox ready up to 40% and approved for non-dedicated EAN use, making it suitable for a broad range of diving scenarios.

The system includes an optional factory-sealed design to prevent outside contamination from silt and sand, protecting performance in underwater environments. It features a pneumatically-balanced poppet, high-flow case and lever design for easy breathing at all depths and tank pressures, plus a hose with a polished 316 stainless steel Atomic Comfort Swivel and Black PVD coating. The dual-material second-stage cover provides full purge access, while the elliptical exhaust valve reduces exhalation effort at depth. The Z2 Octopus offers high-flow second-stage components made of Brass with Zirconium plating and Titanium for reliability, along with a patented Atomic seat-saving orifice for consistent flow in the octopus.
