By merging the distinctive second stage design of Atomic Aquatics in titanium with a first stage featuring a sleek black Diamond-Like Carbon (DLC) over chrome plating, the B2x achieves a remarkable balance.

Utilizing Atomic Aquatics’ proprietary Diamond-Like Carbon 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.

Available in Yoke Unsealed or DIN Unsealed.
