Atomic ST1 Swivel Sealed Regulator, Adjustable Second Stage (Yoke)

A rugged, virtually bulletproof piece of gear, the Atomic Aquatics ST1 Swivel Sealed Regulator is built strong to last a lifetime. Stainless steel delivers virtually the same corrosion resistance as titanium at a lower price. No chrome or nickel plating that can chip off and isn’t particularly environmentally-friendly. The entire first stage is machined from solid 316-grade stainless steel — much stronger than a multi-piece design.
The ST1 regulator’s design uses Atomic’s jet-seat high-flow stainless steel piston mechanism. This exclusive system is self-lubricating for low friction and almost no maintenance. No sharp edges that can damage the seat over time — instead, Atomic employs a conical seat and blunt end piston. Precision-machined valve seats use an extremely strong aerospace-spec material tested for military applications. Among the most reliable seat systems in the industry — this seat can go 2-years or 300 dives without service. Diving performance is superior at even low tank pressure. The ST1 is also freeze protected with a factory sealed first stage that also prevents contamination such as silt and sand from entering the valve mechanism. The regulator is Nitrox ready for mixtures Up to 40% out-of-the-box. The first-Stage has 2 high-pressure (HP) 7/16″ and 5 low-pressure (LP) 3/8″ ports. The LP ports are on a swivel turret for ease of hose routing.
