Atomic Aquatics B2x Unsealed Black

Diamond-Like Carbon (DLC) Coating

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.

B2X Brass & Titanium Regulator

The Atomic Aquatics B2 has earned more awards from independent tests and reviews than any other regulator on the market, gaining fans across the global dive industry. The B2's renowned breathing performance was initially engineered into the T3 and then carried over to the B2x, offering nearly the same level of corrosion resistance. The key difference lies in the metals used in the first stage, which is chrome-plated and then coated with Diamond-Like Carbon (DLC) to enhance corrosion and wear protection.

Patented Automatic Flow Control

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.

Comfort Swivel
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.

The Atomic Aquatics B2x regulator merges the innovative second stage design in titanium with a first stage featuring sleek black Diamond-Like Carbon (DLC) over chrome plating. This combination achieves a perfect balance of performance and durability for scuba divers.

Using Atomic Aquatics’ proprietary DLC process, the B2x regulator offers unmatched tribological properties, making it the most durable and corrosion-resistant brass regulator on the market.
