Great Dives Start Here
You know the moment you mount it on the tank
How can simply turning the tank valve and pressurizing the first stage of your new Atomic regulator be a life-changing experience? Atomic divers characterize it as “confidence.” They realize that a simple twist of the wrist energizes the finest piece of dive equipment made. They are confident that their Atomic regulator will perform perfectly – delivering the first easy, natural breath of their dive...every time they dive. That’s exactly what we expected when we crafted it for you.

Jet Seat Piston
Another Atomic Exclusive
Atomic designed the Jet Seat Piston to eliminate creeping intermediate pressures and minimize maintenance. This unique high-pressure piston seal system is leak-free and self-lubricating.

The Atomic Jet Seat system has no sharp edges that can damage the seat over time, like most competitor's first stages. Instead, Atomic employs a conical seat and blunt-end piston. Our valve seats are precision machined from an extremely strong aerospace specification seat material. This design combination is the most reliable seat system in the industry and enables the seat to go 2-years or 300 dives without service. Diving performance is superior at even low tank pressure.

Features of All Atomic Aquatics First Stages

   Warranty, and 2 year/300 dive service interval

Titanium, SS or Brass...All Are Perfection

T2x First Stage Machined From Solid Bar Titanium

Perhaps by now you know how enthusiastic we are about Titanium. What you may not realize is that the Titanium T2x first stage is precision-machined from a solid piece of material requiring 23 individual operations. The 23 operations are performed in a single continuous milling session at our own Atomica manufacturing facility. That means each body is carefully and expertly crafted under our watchful eyes to conform to only the most exacting standards.

ST1 Stainless Steel “Environmental” First Stage

Beautifully machined from a special grade of solid 316 Stainless Steel, the Atomic ST1 is the world’s first “Green” regulator. The ST1 has the same renowned ergonomics and easy breathing that's designed into all Atomic Aquatics regulators. Stainless steel has twice the strength of brass and is nearly as corrosion-resistant as Titanium. Yet the required resources, energy costs and environmental effects of manufacturing stainless steel give it a distinct ecological advantage over other metals.

B2, Z2/Z2x Brass First Stages Affordable Performance

We understood that not every diver could afford Titanium. Even though every Atomic regulator has all metal second stage components made of Titanium, we designed an affordable first stage using brass. The Atomic difference is the performance, reliable design, and the durable chrome-plating process we developed.

M1 Monel & Brass First Stage Nitrox Ready to 80%

Performance in extreme conditions requires extreme engineering. The Atomic M1 first stage utilizes Monel and Brass for factory-ready Nitrox mixtures to 50% or Oxygen mixes up to 80% when special guidelines are followed. The selection of Monel, which is widely used in marine applications, further demonstrates how adeptly Atomic chooses a material to perform a specific function required by divers.

All Atomic Aquatics first stages are
available in yoke or DIN versions.
