Atomic Aquatics B2 Regulator

The Atomic Aquatics B2 Regulator blends the proven second-stage design of the T3 with a chrome-plated brass first stage, delivering dependable performance for scuba diving and underwater exploration. Built for divers at every level, the B2 pairs robust materials with straightforward operation to support reliable breathing across conditions.

Key features include a brass-first-stage paired with titanium components, patented automatic flow control for stable breathing in diving and scuba environments, and the Atomic Comfort Swivel offering a 30° range of motion to reduce hose binding and kinking. The B2 Comfort Swivel combines polished stainless steel with a black PVD coating (US Patent No. 7,188,869) for long-term durability, delivering performance close to Atomic's T2 in a brass-first-stage package.
