Atomic Aquatics B2 Regulator, Yoke Sealed with Color Kit and Z2 Octo Scuba Diving Package

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.
