Atomic Aquatics B2x Unsealed Black

Atomic Aquatics B2x Unsealed Black is a high-performance regulator set designed for scuba and diving applications. The first stage features a Diamond-Like Carbon (DLC) coating over chrome-plated brass, delivering superior wear resistance and corrosion protection while maintaining smooth operation underwater.

The B2x system combines an all-titanium second stage with an ergonomic first stage and a pneumatically-balanced poppet for easy breathing at all depths and tank pressures. It is Nitrox ready, approved for non-dedicated EAN use with mixtures up to 40%, and includes an option to seal at the dealer to prevent outside contamination from silt and sand—keeping your scuba gear performing reliably in underwater environments.

Designed for straightforward maintenance and reliable performance, the B2x Unsealed Black offers consistent air delivery, a comfortable mouthpiece, and a compact, durable package suitable for both novice divers and experienced divers exploring underwater environments.

• Utilizing Atomic Aquatics’ proprietary DLC process, the B2x attains unparalleled tribological properties unmatched by any other Brass regulator. This ensures supreme durability and corrosion resistance without compromising the seamless operation of the 1st stage. Our DLC coating gives 16X more protection than just the raw metal.
• The original Atomic Aquatics B2 has garnered more awards from independent tests and reviews than any other regulator on the market and with fans in virtually every corner of the dive industry world. The signature breathing performance of the T3 was first engineered into the B2 and then the B2x with virtually the same corrosion-resistance. The difference is the metals used in the first stage, which chrome-plated and then DLC coated to increase corrosion and wear protection.
• You shouldn’t have to think about breathing when you dive. The exclusive Atomic AFC helps you breathe naturally at any depth without thinking about adjusting. The Atomic AFC eliminates the manual adjustment normally needed to regulate Venturi effect as you dive deeper. No dials to turn or buttons to push. A Rapid Adjustment Knob is included for special situations like surf entry or octo use.
• Divers deeply admire many exclusive features of Atomic Aquatics second stages that make diving easier. One of the most acclaimed is the Atomic Aquatics Comfort Swivel which allows 30° rotational movement without hose binding or kinking. The B2x stainless steel Comfort Swivel with black PVD coating for great corrosion-resistance. Once you dive more comfortably with it, you’ll wonder why no one else ever thought of it.
